TEST: have key_unsupported() in evp_test.c look at the last error

key_unsupported() looked at the first error in the queue to see if a
key algorithm is supported or not.  However, there are situations
where the errors it looks for is preceded by others.  It's much safer
to look at the last recorded error.
