avformat/(aiff|flac|mov|mp3|tta)enc: Don't create unnecessary references

Browse Source 
The packet given to muxers is not used afterwards; it is always
unreferenced by libavformat. Ergo muxers are allowed to keep
the references in the packets and e.g. move the ownership to
a packet list. This is what this commit does.
