Subject: [PATCH] [rubygems/rubygems] Add `Gem::Specification#gem_dir` back

If old Bundler versions that unconditionally try to remove this method
are run with RubyGems versions _without_ this method, Bundler crashes
because it tries to remove a method that does not exist.

We need to wait until RubyGems cannot install any Bundler versions that
unconditionally remove this method.
