[rubygems/rubygems] Stop bundler eagerly loading all specs with exts

We were setting the wrong `extension_dir` for git specs stubs

Additionally, the call to `self.extension_dir` was loading the
remote spec, which was avoidable since the stub had an extension dir
(and in fact its #gem_build_complete_path does exactly what we want
anyway)

Finally, now set the base_dir when loading the remote_spec from a
stub specification, since the git source sets the base dir for stubs
based on where the spec _will_ be installed to, and we want to preserve
that so the base_dir for the loaded spec & the stub are the same
