evp_test: Add the missing check after calling OPENSSL_strdup and sk_OPENSSL_STRING_new_null

Since the memory allocation may fail, the 'mac_name' and 'controls'
could be NULL.
And the 'mac_name' will be printed in mac_test_run_mac() without check.
Also the result of 'params_n +
sk_OPENSSL_STRING_num(expected->controls)' in
mac_test_run_mac() will be 'params_n - 1' if allocation fails , which
does not make sense.
Therefore, it should be better to check them in order to guarantee the
complete success of initiation.
If fails, we also need to free the 'mdat' to avoid the memory leak.
