wm4 8bf4a60bbe VF: remove IMGFMT_MPEGPES
This wasn't used anymore.

Remove the reference to IMGFMT_MJPEG in vf_dlopen as well. Thus format
is used as FourCC in the TV code (i.e. it's on the demuxer level, just
like raw formats), and never appears in the video filter chain. For
starters, vd_ffmpeg can never produce this format.
