Bug 4111: leave_suid() does not properly handle error codes returned by setuid

... this will cause privilege escalation in the rare case that setuid fails.
So far there are no known cases of this happening when downgrading from root.

Also fixes several incorrect uses of errno which may have been obscuring
error message details if it did happen.
