sgx-ssl: split out tests. build-only by default.
- Normally SGX has a SIM mode for running enclave tests on non-Intel SGX capable hardware; however, these tests do some tricky stuff with cpuid and CPU trap handling that make them non-portable. - This diff makes it so OfBorg (which can't _run_ the tests) at least builds them. The tests are also split out into a separate derivation to save my sanity when iterating on them, since sgx-ssl takes like 30 min to build...
