LibGfx/JPEG: Don't fail to decode images with non-compliant ICC profile

Some images (like https://www.w3.org/Press/Stock/Berners-Lee/2001-europaeum-eighth.jpg)
embed a non-compliant ICC profile. Instead of rejecting the image, we
can simply discard the color profile and resume the decoding of the
bitmap.
