intel-media-driver: Fix runtime issues due to the libX11 dependency

X11 is an optional run-time and optional build-time dependency of iHD.
A patchelf is required to join these two worlds together, and a lot of
machines that'll run the intel-media-driver won't have X11 on them, so
make it optional.

Fix #73236.
