macOS, FFmpeg: Explicitly do not link X11 libraries

The FFmpeg auto-detect mechanism will automatically pull in x11 as a
dependency if the development packages are found on the host. This makes
the FFmpeg unable to run macOS hosts that don't have the x11 package
installed.

This patch makes us explicitly avoid including it.
