* lib/rubygems: Update to RubyGems master ddac51f. Changes:

  * Allow override for the shared gem installation directory for
    rubygems packagers.

  * Lock gem cache files for read and write to improve thread safety.

  * Use io/console when available.

  * Minor cleanup.

* test/rubygems:  ditto.
