ruby/rubyv2: add new rubyv2 bbclass and support external extconf

When building/installing gems with native components, the target
OS and cross compile settings were not correctly being picked up.

Enhance the existing bbclass with the ability to copy a extconf.rb
from UNPACKDIR, so a recipe can specify fixes in it's own copy of
the file.

We also bring in a class from meta-rubygems which has more advanced
cross compile settings. There are a few minor modifications to
this class (copying of extconf.rb) and some spec generation. But
it is now available if the basic ruby class cannot compile and install
a gem.
