utimens: introduce fdutimens
at-func.c wants the file name argument first. This also paves the
way to add fdutimensat(dfd,name,fd,times,flag).
* lib/utimens.h (fdutimens): New prototype.
* lib/utimens.c (gl_futimens): Move guts...
(fdutimens): ...to new interface.
* tests/test-utimens.c (do_fdutimens): Use it.
