Alyssa Ross 16591184b4 nixos/no-x-libs: remove X libs from ffmpeg
Prior to this change, ffmpeg couldn't be built for an
environment.noXlibs system, because it would fail in:

	ffmpeg → SDL2 → libdecor

ffmpeg certainly does not need support for SDL2 windowing on a noXlibs
system.

This fix is important because the minidlna NixOS test, which uses the
minimal profile (and therefore environment.noXlibs) and ffmpeg, can't
currently build.

Switch off the options in the default configuration that
require X11 libraries. This includes client-side font
configuration and SSH forwarding of X11 authentication
in. Thus, you probably do not want to enable this option if
you want to run X11 programs on this machine via SSH.
