touch: Use special UTIME_NOW and UTIME_OMIT values

This allows users to touch files they have write access to, but aren't the
owner.

Also, remove utime.h include (not necessary since
4132561c1729df9440a6ae2566a0cccadcccf860), and make sure to check the return
value of localtime (potentially preventing a NULL pointer derefence).
