rust-matchers: remove default implementations for `Matcher` trait

We don't expect a whole lot of matchers to be defined, and this makes it more
obvious what a matcher does by reading its `impl Matcher for FooMatcher`.

This patch has the added benefit of fixing the `AlwaysMatcher`, its `matches`
function differs from the former default.
