[LTP] [PATCH 2/2] request_key/request_key02.c: add new testcase

[Xiao Yang]

1) request_key(2) fails if no matching key was found and
   set errno to ENOKEY.
2) request_key(2) fails if a revoked key was found and
   set errno to EKEYREVOKED.
3) request_key(2) fails if an expired key was found and
   set errno to EKEYEXPIRED.
