Add homebrew_tap native type

This is not at all about optimization. In cases where homebrew is invoked via the same Ruby version as is running Puppet, the bundled environment can cause homebrew to shit the bed a little.

This adds a native type to make use of the existing bundled_environment feature in this module to make sure brew tap executes in a clean environment.

homebrew::tap is still here, but now just wraps homebrew_tap.
