[Linux] Use av_log_set_callback() for ffmpeg logging to bypass RDD sandbox.

I'm not sure what you had in mind for getting around it. Disabling the internal logging? That'd work but might make debugging trickier.

As pointed out in the original bug, this might be a matter of moving the code to handle libavcodec to the RDD process: https://searchfox.org/mozilla-central/source/security/sandbox/linux/SandboxFilter.cpp#1288

I misread the original post https://bugzilla.mozilla.org/show_bug.cgi?id=1693083#c2
If the crash happens with MOZ_LOG only we don't need that.
Thanks.
