Subject: [PATCH] fftools/ffmpeg_enc: set AV_PKT_FLAG_TRUSTED on encoded
 packets

This allows using WRAPPED_AVFRAME encoders with loopback decoders in
order to connect multiple filtergraphs together.

Clear the flag in muxers, since lavf does not need it for anything and
it would change the results of framecrc FATE tests.
