swscale/yuv2rgb: fix conversion for widths not aligned to 8

Browse Source 
The C code for some pixel formats (rgb555, rgb565, rgb444, and monob)
was not converting the last pixels on widths not aligned to 8.

NOTE: the last pixel for odd widths is still not converted for any of
      the pixel formats in the C code for yuv2rgb except for monob.
