* lib/rubygems: Update to RubyGems master b9213d7. Changes include:

Fixed tests on Windows (I hope) by forcing platform for
  platform-dependent tests.

  Fixed File.exists? warnings.

  Improved testing infrastructure.

* test/rubygems:  ditto.

* test/rdoc/test_rdoc_rubygems_hook.rb:  Switch to util_spec like
  RubyGems.
