bits/user.h: provide an empty header for inclusion by <sys/user.h>.

At the present, there seems to be no need to provide struct user,
or any other debugging structure for that matter, from within libc.

This conclusion follows examination of the gdb and llvm sources,
and will be confirmed once the above have been ported to midipix.
