xfs: encode the rtbitmap in little endian format

Currently, the ondisk realtime bitmap file is accessed in units of
32-bit words.  There's no endian translation of the contents of this
file, which means that the Bad Things Happen(tm) if you go from (say)
x86 to powerpc.  Since we have a new feature flag, let's take the
opportunity to enforce an endianness on the file.

The natural format of a bitmap is (IMHO) little endian, because the byte
offsets of the bitmap data should always increase in step with the
information being indexed.
