dev-lang/ruby: properly remove default gems

In Gentoo we always expect the default gems to be present as gems, and
the default gems need to be removed to avoid duplicate definitions in
code that does not explicitly require the gem. json and did_you_mean
were not or only partially removed.

Closes: https://bugs.gentoo.org/758464
