Unit tests don't test non-debug attestation validation

[rjzak]

When debug mode is disabled, such when the certificate isn't self-signed, SGX and SNP have additional checks. Both add an additional check there the hash of the public key from the Certificate Request is expected to be in the body of the attestation report. Additionally, the stored test data for SGX & SNP have bogus data in the respective fields:

• SGX: report.reportdata = 000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f
• SNP: report.body.report_data = 000102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f202122232425262728292a2b2c2d2e2f

We'll need the saved public key data, and new saved attestation reports for unit tests to pass when not in debug mode.
