avcodec/mpegvideoenc: Remove ineffective [pb]bias options

Browse Source 
The user-provided value is overwritten in ff_mpv_encode_init()
without having ever been read.
(This has been broken when making these options mpegvideo-specific
in commits 910247f1720c6aae422723c05dac6d0b19f20bec and
cf7d2f2d2134c0854edf2db91e7436ac2bc9874f. No one has ever complained,
so this commit removes these fields.)
