grsecurity: discontinue support
Upstream has decided to make -testing patches private, effectively ceasing
free support for grsecurity/PaX [1].  Consequently, we can no longer
responsibly support grsecurity on NixOS.

This patch turns the kernel and patch expressions into build errors and
adds a warning to the manual, but retains most of the infrastructure, in
an effort to make the transition smoother.  For 17.09 all of it should
probably be pruned.

grsecurity: enable optional sysfs restrictions
Fairly severe, but can be disabled at bootup via
grsec_sysfs_restrict=0. For the NixOS module we ensure that it is
disabled, for systemd compatibility.

grsecurity module: force a known good kernel package set
Previously, we would only set a default value, on the theory that
`boot.kernelPackages` could be used to sanely configure a custom grsec
kernel.  Regrettably, this is not the case and users who expect e.g.,
`boot.kernelPackages = pkgs.linuxPackages_latest` to work will end up
with a non-grsec kernel (this problem has come up twice on the bug
tracker recently).

With this patch, `security.grsecurity.enable = true` implies
`boot.kernelPackages = linuxPackages_grsec_nixos` and any customization
must be done via package override or by eschewing the module.

grsecurity module: remove requiredKernelConfig
Using a custom package set with the NixOS module is no longer
something I wish to support.  It's still *possible* but not
advertised.  Secondly, the requiredKernelConfig didn't really
do anything (setting kernelPackages to a non-grsec kernel would
just silently let the user boot into a non-grsec setup ...).

grsecurity: make GRKERNSEC y and PAX y implicit
These options should always be specified. Note, an implication of this
change is that not specifying any grsec/PaX options results in a build
failure.
