Why does this code use <sys/inttypes.h> instead of <inttypes.h>?

Note, that PRIxREGISTER and other kernel PRIx* macros are, for better
or worse, not coming from inttypes headers, but from
<machine/types.h>.  But they can be deined in terms of standard PRIx*
macros and for the userland code those are officially defined by
<inttypes.h>.
