tesseract: Package version 4.x from Git master
Tesseract 4 has got a new long short-term memory neural networking based
OCR engine which really helps a lot in terms of accuracy and our VM
tests.

I ran the new version across a bunch of different screenshots and
comparing the results to the 3.x branch and it really makes a big
difference, especially with various font rendering settings.

The only downside of this is that version 4 hasn't been released yet and
is in alpha state right now, but it will eventually get there and the
only solutions that came into my mind sticking to version 3 were really
sub-par:

 * Use several passes with different color negation on the screenshots.
 * Train Tesseract 3 specifically for screenshots. This is sub-par
   because we'd need to do it for Tesseract 4 from scratch again.
 * Change the test systems so that it specifically uses *only* OCR an
   font when displaying. I've actually tried this but this also isn't
   accurate enough with our default font rendering setup.
 * Turn off special font rendering settings for our tests. In
   conjunction with changing to an OCR font this might work but it won't
   catch all the cases, because applications might use their own font
   rendering.

Given that version 4 is faster[1] when it comes to OCR detection and also
the points just mentioned I think even using the alpha version just for
tests isn't going to hurt anybody.

tesseract: 3.04.01 -> 3.05.00
Upstream changelog:

 * Made some fine tuning to the hOCR output.
 * Added TSV as another optional output format.
 * Fixed ABI break introduced in 3.04.00 with the AnalyseLayout()
   method.
 * text2image tool - Enable all OpenType ligatures available in a font.
   This feature requires Pango 1.38 or newer.
 * Training tools - Replaced asserts with tprintf() and exit(1).
 * Fixed Cygwin compatibility.
 * Improved multipage tiff processing.
 * Improved the embedded pdf font (pdf.ttf).
 * Enable selection of OCR engine mode from command line.
 * Changed tesseract command line parameter '-psm' to '--psm'.
 * Added new C API for orientation and script detection, removed the old
   one.
 * Increased minimum autoconf version to 2.59.
 * Removed dead code.
 * Fixed many compiler warning.
 * Fixed memory and resource leaks.
 * Fixed some issues with the 'Cube' OCR engine.
 * Fixed some openCL issues.
 * Added option to build Tesseract with CMake build system.
 * Implemented CPPAN support for easy Windows building.

The upstream URL of the change log is:

https://github.com/tesseract-ocr/tesseract/releases/tag/3.05.00

Tested by building against the following packages that directly depend
on it:

 * vapoursynth (with ocrSupport = true)
 * pyocr (fails)
 * vobsub2srt

Also tested against the following NixOS VM tests that have OCR enabled:

 * nixos/tests/chromium.nix -A stable
 * nixos/tests/emacs-daemon.nix
 * nixos/tests/installer.nix -A luksroot
 * nixos/tests/lightdm.nix
 * nixos/tests/plasma5.nix
 * nixos/tests/sddm.nix

All of the packages and tests except pyocr build/succeed on
x86_64-linux.

Fixing pyocr is outside of the scope of this commit and will happen very
soon.

tesseract: Reintroduce enableLanguages
I've removed that attribute in 68bc260ca2,
because the language files no longer were distributed as seperate files,
but if we for example only want to use the English training data, the
closure size of Tesseract gets quite large (around 1.2 GB), which is a
bit much just to be able to run NixOS VM tests.

For this reason I've also switched the VM tests back to using only the
English language.

Tested using the following VM tests (the ones that have OCR enabled) on
x86_64-linux:

 * nixos/tests/chromium.nix -A stable
 * nixos/tests/emacs-daemon.nix
 * nixos/tests/installer.nix -A luksroot
 * nixos/tests/lightdm.nix
 * nixos/tests/plasma5.nix
 * nixos/tests/sddm.nix
