FFmpeg: Get non-monolithic libav* filenames from libavformat.

Browse Source 
The non-monolithic libavformat is linked against libavcodec and libavutil.
Instead of (falsely) guessing the filenames of libavcodec and libavutil, get the
files that the libavformat library is linked against. This fixes wrong filename
guesses and avoids run-time issues by using incompatible libavcodec/libavutil
version with libavformat.
