[rubygems/rubygems] Restore gem_dir
as an instance variable accessor
I suspect someone could be setting this instance variable, and the previous changes made that no longer effective. Also I implemented a previous TOOD in `full_gem_path` the other way around: > # TODO: This is a heavily used method by gems, so we'll need > # to aleast just alias it to #gem_dir rather than remove it. I made `gem_dir` an alias of `full_gem_path` rather than the opposite. This alternative change keeps both methods symmetric without deprecating either of them for now. https://github.com/rubygems/rubygems/commit/28983973a3
