dev-ruby/rubygems: new Gentoo defaults

This revision has pretty much completely rewritten Gentoo defaults for
ruby. The old defaults were broken with the introduction of default gems
in rubygems 3.0.0. The new defaults should be backward compatible with
the old defaults, but they use defined hooks for the most part to do the
work.

+# Gentoo defaults for rubygems 3.x
+#
+# Gentoo policy is to install all manually installed code into
+# /usr/local and to keep /usr managed by Gentoo. This policy file
+# ensures that all manually installed gems using "gem install" are
+# installed in /usr/local. Gentoo gems are installed in /usr.
+
+# TODO: We used to manipulate the default_dir, but this no longer
+# works since this is now the base for the new "default" gems that
+# ruby 2.6 uses with irb. So default_dir should refer to the system
+# default now. rubygems also provides various hooks so we may be able
+# to use those to install gems in /usr/local by default in a less
+# intrusive way.
