In this patch, a very simple test is added to verify that rsa_verify() using rsa_verify_with_pkey() work correctly.
To keep the code simple, all the test data, either public key and verified binary data, are embedded in the source.

This test should depend on RSA_VERIFY_WITH_PKEY because is cannot be executed otherwise.
When on qemu_arm64_defconfig I select all of the above mentioned configs I get a build error:
