Provide a harness driving rust-openssl's regress tests
rust-openssl is an integral part of the Rust ecosystem and more than a
dozen ports, including lang/rust itself, depend on it. We need to ensure
that it keeps working with LibreSSL.
If the rust and rust-openssl-tests packages are installed, create a cargo
workspace under obj/ that compiles and runs the rust-openssl regress tests
much like what is done for the openssl-ruby tests. This expands our regress
coverage: for instance, this would have caught the broken ASN.1 indefinite
length encoding caused by asn1/tasn_enc.c r1.25.
