Skip IdentityCredentialTests using attestation on GSI.

For RKP to return attestations, the `remote_provisioning.hostname`
property needs to be set to the proper hostname to query for attestation
certs.

GSI doesn't set this property, so these tests fail on RKP-only devices.

This amends ag/34234496
