This allows me to use Supermicro's BMC, which appears to drop a
stunnel binary into /tmp and then execute it, which doesn't work
properly in Nix because nothing is where it is expected to be.
Summary:
Adds porcorosso to the depot, and also adds the supporting Nix architecture required to make this work.
This also tests that encryption is working correctly.
