Since wine-4.4, Windows XP's cmd.exe doesn't execute batch files anymore, it
simply silently fails and does nothing. A regression test pin-pointed the
issue:

advapi32: Add a stub implementation of SaferIdentifyLevel.

Reverting the patch to a stub is necessary. Changing the return value to FALSE
does not work. I'm not sure how else to fix this since it's just a stub, and
similar stubs (like SaferComputeTokenFromLevel) don't seem to have a problem.
Having those return FALSE doesn't seem to help either.
