Fake libraries for gem builds?

[Vít Ondruch]

Hi everybody,

Looking at omniauth PR [1], I just realized that on a lot of places, we
remove references to SimpleCov, Coveralls, Bundler and probably others
to cut down the dependencies. What if we shipped in rubygems-devel some
fake libraries, which would try to load the original library, but
silently provided the miminum mock to make the test suite pass without
the library?

E.g. for rubygem-omniauth and Coveralls, we would have:

~~~
$ cat /usr/share/ruby/vendor_ruby/coveralls.rb
begin
  gem 'coveralls'
  require 'coveralls'
rescue LoadError
  puts '!!! Mocking Coveralls !!!'
  class Coveralls
  end
end
~~~

This is just an idea. I have not tested it. WDYT?
