tests.buildRustCrate: add crateLibOutputsWasm32

Browse Source 
Added a cross compilation test for wasm32-unknown-unknown. This also
required using crate.metadata instead of using the regex to get rid of
the hash in the library filename. It also required adding a mkCrate
argument to assertOutputs so we can override the buildRustCrate used.
