Title: Ignore rubinius-only gems when running bundle install --local on MRI

This is a fix for #2774. Probably, there are other cases like it which require a more thorough fix. For example, I'm guessing Bundler will try to find MRI 1.8-only gems when installing under MRI 2.0. I'll comment more on this later.
