media: don't let Farstream use VA-API elements
Video Acceleration API isn't well supported in Farstream and produces
errors during video calls, however a high Rank of vaapi GStreamer
elements causes them to be picked as preferred video encoders and
decoders when available in the system.
For now, set the rank of all elements from vaapi plugin to NONE, so that
they are ignored.
Backport of Pidgin 3 commit 1e3a33f69fab.
