libsandbox: fix utimensat regression with NULL filename
The previous commit (libsandbox: handle dirfd in mkdir/open/unlink *at
prechecks) unified some path checks while unifying the dirfd code, but
prevented valid NULL paths from also being handled. Make sure we still
handle that behavior, and add a test for it to prevent future regressions.
