test.rs: Split `build_alias` test into 5 separate tests

Instead of putting all our asserts in a single test function, make a
function for each assert. This allows us to give our test functions more
specific names based on what exactly we're testing, and produces better
output from `cargo test`. Also, if one of those fails for whatever
reason, it's nice to know it will do so with a meaningful name.
