libglvnd: Improve the license information (#114466)
Unfortunately the upstream licensing is quite complicated:
https://gitlab.freedesktop.org/glvnd/libglvnd#libglvnd

The main libglvnd license is MIT-like but files under different licenses
are also included. This is an approximation that ignores some license
"customizations".

Other distributions use the following license specifications:
- "MIT":
  - https://src.fedoraproject.org/rpms/libglvnd/blob/rawhide/f/libglvnd.spec
  - https://build.opensuse.org/package/view_file/openSUSE:Factory/libglvnd/libglvnd.spec
  - https://gitweb.gentoo.org/repo/gentoo.git/tree/media-libs/libglvnd/libglvnd-1.3.2-r2.ebuild
- "custom:MIT-alike": https://github.com/void-linux/void-packages/blob/master/srcpkgs/libglvnd/template
- "APACHE20 MIT": https://www.freshports.org/graphics/libglvnd
- "custom:BSD-like": https://archlinux.org/packages/extra/x86_64/libglvnd/

longDescription = ''
libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API
calls between multiple vendors. It allows multiple drivers from different
vendors to coexist on the same filesystem, and determines which vendor to
dispatch each API call to at runtime.
Both GLX and EGL are supported, in any combination with OpenGL and OpenGL ES.
