win32: skip ACL check in stat(2) when running as rootFRP-4881-ga6c5fd4eb

Commit 88965fe20 (win32: use ACL check to clarify write permission)
added code to check if a file had write permission due to an ACL
entry.

When running with elevated privileges this check is unnecessary as
"user" permissions will be sufficient.  This also prevents write
permission for "other" being set without respecting umask.
