* lib/rubygems: Update to RubyGems master 3de7e0f. Changes:

  Only attempt to build extensions for newly-installed gems.  This
  prevents compilation attempts at gem activation time for gems that
  already have extensions built.

  Fix crash in the dependency resolver for dependencies that cannot be
  resolved.

* test/rubygems:  ditto.
