[rubygems/rubygems] Ignore local specifications if they have incorrect dependencies

Currently ruby-dev installs an incorrect gemspec for rdoc, that does not
declare its dependency on psych.

This seems like a ruby-core bug, but it seems best for Bundler to ignore
it, go with the remote specification instead, and print a warning.
