Activate check for SGX report status

[Niederb]

When verifying an SGX report we need to make sure that the report has an acceptable status. The status is not stored in the state and therefore cannot be checked again later. The needed code is already there but currently not active. Note that the teeracle on devsgx03 would currently not pass this check and we need a solution for that before activating the check.
See in teerex/src/lib.rs:

// TODO: activate state checks as soon as we've fixed our setup
// ensure!((report.status == SgxStatus::Ok) | (report.status == SgxStatus::ConfigurationNeeded),
//     "RA status is insufficient");
// log::info!("teerex: status is acceptable");
