Drop -rubygems flag, add --no-document flag

Do the following:

* Drop `-rubygems` from `ruby -rubygems -e 'pus Gem.default_dir'`. This
  flag appears to no longer be supported.
* Drop `makedepends=(rubygems)`. This dependency now resolves to the
  "ruby" package, and the error above suggests that rubygems is no
  longer a separate package.
* Add `--no-document` to `gem install ...`. This fixes a `cannot load
  such file -- rdoc/rdoc` error. It's also the approach taken by the
  ruby-hpricot community package.
