fix keyutils test error report

Upstream-Status: Pending

"Permission denied" may be the reason of EKEYEXPIRED and EKEYREVOKED.
"Required key not available" may be the reason of EKEYREVOKED.
EXPIRED and REVOKED are 2 status of kernel security keys features.
But the userspace keyutils lib will output the error message, which may
have several reasons.
