ruby: break out ri-docs and rdoc into separate packages

The ri (Ruby Interactive) documentation for the Ruby standard library
consumes a significant amount of space on disk. It is useful to
developers, but is usually not necessary for users who just want to run
applications written in Ruby.  Break it out into a separate package so
Ruby can be installed without it.

Also break out the rdoc documentation generator in its own package.
