checkasm/sw_rgb: also test yuyvtoyuv422
yuyvtoyuv422 reads the trailing odd V sample at src[2w+1], one byte further
than uyvytoyuv422, so the number of extra source bytes an odd width needs is
passed in per format (1 for UYVY, 2 for YUYV) and added to the stride.

uyvytoyuv420 and yuyvtoyuv420 are intentionally not added: their x86 mmxext
chroma averaging uses PAVGB rounding and so is not bit-exact with the C
reference, which truncates, so they cannot be verified this way.
