[PATCH v2] dix: Fix image byte order on big endian hardware

[Olivier Fourdan]

Make sure X_BIG_ENDIAN/X_LITTLE_ENDIAN are defined before actually using
them.

Otherwise, image byte order could be wrong on big endian hardware even
though endianess detection is correct.

 v2: Simply include X11/Xarch.h in servermd.h to make sure
     X_LITTLE_ENDIAN/X_BIG_ENDIAN are defined when we need them.
