libgpiosim was not meant to be installed for development, that's why
there's no pkg-config for it. We don't install the header and only
install the shared object if tests are enabled but with the
expectation that the tests were built in-tree.

I also don't quite get why we'd want to get gpiosim via crates.io - I
would prefer to use the one in the tree. Or am I not understanding
something here right?
