Don't use _mesa_swizzle_ubyte_image if all three texture formats
involved in _mesa_textore_argb/rgba8888 (source, base-internal,
destination) differ. _mesa_swizzle_ubyte_image knows only about two of
the formats and can't handle the case that all three are different
correctly. Fixes https://bugs.freedesktop.org/show_bug.cgi?id=3111.
