xtest: regression 4006: Test RSA-OAEP with a different MGF1 hash

[samitolvanen]

Add tests for TEE_ALG_RSAES_PKCS1_OAEP_MGF1_SHA256 with SHA-1 as the MGF1 hash.

Depends on OP-TEE/optee_os#6779. Note that this fails (as expected) with mbedtls.

We need to have this as a separate test case (for example, regression_4006_1) so that it can be excluded from the run when MbedTLS is used as the core crypto lib:

make -j$(nproc) check CFG_CRYPTOLIB_NAME=mbedtls CFG_CRYPTOLIB_DIR=lib/libmbedtls XTEST_ARGS="-t regression -x regression_4006_1"

Another option is to accept the TEE_ERROR_NOT_SUPPORTED error as a valid response (and skip the subtest) when TEE_ATTR_RSA_OAEP_MGF_HASH doesn't match the internal hash algorithm.

@jenswi-linaro that would work with me

Alright, I decided to go with this option. PTAL.
