* lib/rubygems: Update to RubyGems master 50a8210. Important changes

  in this commit:

  RubyGems now automatically checks for gem.deps.rb or Gemfile when
  running ruby executables.  This behavior is similar to `bundle exec
  rake`.  This change may be reverted before Ruby 2.1.0 if too many bugs
  are found.

* test/rubygems:  ditto.
