Make it easier to review updates to `sgx-{sdk,psw}` on machines with
actual SGX hardware support. The passthru tests build and run the SGX
samples in simulation mode which works without any hardware support. To
run the samples on a machine with SGX hardware support, issue the
following command:
```bash
$(nix-build -A sgx-sdk.runTestsHW)/bin/run-tests-hw
```
Make sure the SGX AESM daemon is running as some tests require it. See
the `services.aesmd.*` NixOS module options and the `sgx-psw` package
for details.
