This removes locales, bash completion and crap like that. This cuts
6.5 MiB from the NixOS system closure (which unfortunately contains
two copies of util-linux, because of the need to break a dependency
cycle with systemd).
Fixes build against dpdk 16.06
Tested build against linux, linux_latest, linux_3_18, linux_4_1,
linux_4_6, linux_grsec_nixos, linux_chromiumos_3_18.
While this is pre-release, the delta since 10.10.1.0 seems to contain
primarily fixes or internal improvements.
Also cleanup build inputs while we're at it.
Looks to be incompatible with the PaX constification plugin:

This prevents systemd and by extension a zillion other packages from
having Python 2.7 in their closure. For example, the closure of
systemd dropped from 133 MiB to 85 MiB.
With the default kernel and thus with the build I have tested in
74ec94bfa2, we get an error during
modules_install:
make[2]: execvp: /nix/store/.../bin/bash: Argument list too long
I haven't noticed this build until I actually tried booting using this
kernel because make didn't fail here.
The reason this happens within Nix and probably didn't yet surface in
other distros is that programs only have a limited amount of memory
available for storing the environment and the arguments.
Environment variables however are quite common on Nix and thus we
stumble on problems like this way earlier - in this case Linux 4.8 - but
I have noticed this in 4.7-next as well already.
The fix is far from perfect and suffers performance overhead because we
now run grep for every *.mod file instead of passing all *.mod files
into one single invocation of grep.
But comparing the performance overhead (around 1s on my machine) with
the overall build time of the kernel I think the overhead really is
neglicible.

Tested by only building the linux_testing attribute, but haven't yet
tested it in production.
I've also fixed the extraMeta.branch attribute.

Previously, features.grsecurity wasn't actually set due to a bug in the
grsec builder. We now rely on the generic kernel builder to set features
from kernelPatches.
Upstream
e71a5fc58c
adds linux 4.7 support; all subsequent commits are error fixes so we
bump to current HEAD for good measure.
Built against linux and linux_latest.
Mark as broken on -grsec, seems incompatible with PaX
constification:

and so on.

This doesn't change the resulting x86 configs, but is more useful for
other architectures. For instance, POSIX_MQUEUE is currently missing
on ARM.
