Michael Niedermayer 321c3cd1a9 avformat/img2dec: reduce bmppipe probe score
bmp pipe needs the bmp parser which is not bug free and should thus not be favored
over the bmp image2 demuxer
that also means this change could be reverted in case bmp pipe is improved so it
handles all single bmp images correctly
