st/mesa: Fix handling of LA and RG formats for big-endian

Browse source 
MESA_FORMAT_LnAn puts the luminance in the least significant part of
the containing integer, which is equivalent to PIPE_FORMAT_LAnn.
PIPE_FORMAT_LnAn puts the luminance first in memory.

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