progs: clean up all remaining xfs*h includes

Convert all the various ways of including xfs*.h to one standard
way across all libraries and utilities:

#include "xfs/xfs*.h"

This means we are consistently including the local
include/xfs/xfs*h header file in parts of the build.

The exception to this is the libxfs/ directory, which does not use
the "xfs/" prefix in files shared with the kernel to maintain as
much similarity to the kernel code as possible. However, libxfs/ is
the source that include/xfs points back to, so the local include
rule ensures this works just fine.
