Do not look for `Cargo.toml` inside `target`

This test, which checks that we do not define new profiles directly in
Clippy's multiple `Cargo.toml` files, must not look inside `target` as
`lintcheck` might place some third-party sources there. Of course those
third-party sources are allowed to define profiles in their `Cargo.toml`.
