st/mesa: Fix handling of 8888 SNORM and SRGB formats for big-endian

MESA_FORMAT_x8y8z8w8 puts the x channel in the least significant part of
the containing 32-bit integer, which is equivalent to PIPE_FORMAT_xyzw8888.
PIPE_FORMAT_x8y8z8w8 puts the x channel first in memory.

This patch fixes up the mesa<->gallium mapping accordingly.
