dix: Remove arch awareness from servermd.h (v2)

Browse Source 
At this point we have no architectures where image byte order is
different from bitmap bit order, or where either of those two are not
also the native word endianness.  Hooray, one more place where we don't
have to worry about enabling new CPU architectures.

v2: Rebase to master to handle the addition of ppc64le, arc, and xtensa,
and use autoconf's endianness detection instead of gcc predefines.
