buildRustCrate has a handy `include` helper, that only imports those whitelisted files and folders to the store. However, the function's matching logic is broken and includes all files, regardless of whether or not they're whitelisted, as long as the whitelist contains at least one name (regardless of whether that name exists). This is because it doesn't take into account that `lib.strings.removePrefix "foo" "bar" == "bar"` (that is, paths that don't match the prefix are passed straight through).
