Subject: [PATCH] Fix phutil_analyzer bug on interface dependency creation

Summary:
Use $interface_name instead of $class_name when dealing with
interfaces. Problem happens when you extend an interface:

    interface SubIface extends SuperIface { ...

    Notice: Undefined variable: class_name in ...
	Fatal error: Call to a member function getConcreteString() on a
	non-object in ...

Test Plan: phutil_mapper.php works!
