Rely on the build environment rather than use MacOS.locate

Our build environment setup ensures these tools will be on the PATH,
so we shouldn't use private API to find them.

Simplify conditions for superenv activation

`MacOS::Xcode.without_clt? && MacOS.sdk_path.nil?` should never be true.

In its earliest form, this would raise a bare RuntimeError in an effort
to have the bug reported. Later, it was changed to silently disable
superenv. But we don't want to do that. If there's a bug, or the user's
system is misconfigured, we want to know, so that we can fix the bug, or
the user can fix their system. So let's remove the condition.
Only directories are candidates for superenv bin
