Title: add RUBYLIB=lib/ruby/vendor_ruby to setup.bash for ruby programs

I want to add ruby library path for setup.sh.

I'm releasing rosruby, and it needs additional environmental variable " RUBYLIB=/opt/ros/hydro/lib/ruvy/vendor_ruby".
If catkin_init_workspace supports this variable generation, it is more easy to use ros ruby libraries.
