virfile: Add extra check for direct delete in virFileRemove

Unlike create options, if the file to be removed is already in the
pool, then the uid/gid will come from the pool. If it's the same as the
currently running process, then just do the unlink/rmdir directly
rather than going through the fork processing unnecessarily
