Title: use separate gemspec for mingw

- allows us to explicitly version pin in the gemspec on gem installs
rather than getting different behavior from 'gem install' and
'bundle install' (gemspec vs. Gemfile).
- the mingw deps had been in the Gemfile because it needed to be a
group since gemspecs do not have groups. this builds two different
gems for publication to rubygems instead.
- see mixlib-shellout for the prototype of where this has been done
(successfully).
