crypto-tester: Don't fail if key size is not supported

The Blowfish and Twofish implementations provided by the gcrypt plugin
only support specific key lengths, which we don't know when testing
against vectors (either during unit tests or during algorithm
registration).  The on_create test with a specific key length will be
skipped anyway, so there is no point in treating this failure differently.
