Refactor scalap's main

The structure of scalap's Main has been refactored.

EmptyClasspath is deleted. It looks that it was unused since this
commit: https://github.com/scala/scala/commit/e594fe58ef8116a4bd2560ad0a856ad58ae9db33

Also classpath logging is changed and now uses asClassPathString
method. It was needed to modify one test because of that but it
won't depend on a particular representation.

There aren't changes in the way scalap works.
