[Buildroot] [NEXT v2 4/7] libpjsip: enable ffmpeg support

[Adam Duskett <aduskett@gmail.com>]

If FFmpeg is selected, libpjsip should depend on it.
Specifying --with-ffmpeg= is necessary because passing --enable-FFmpeg
actually disables FFmpeg when cross compiling.

Changes v1 -> v2:
  - Remove the option to enable or disable FFmpeg support in favor of
    just depending on FFmpeg if it's selected by the user.
  - Add explination as to why with-ffmpeg is being passed to libpjsip (Arnout)
