fftools/ffmpeg_enc: move set_encoder_id() to ffmpeg_mux_init

Browse Source 
This code uses no encoder properties or state besides its name, and is
mostly muxer logic, and thus belongs more properly into the muxer.

The results of several test change due to different metadata tag order
(the "encoder" tag is now set first).
