Check that BASERUBY is at least Ruby 2.2 in configure

Browse Source 
BASERUBY needs to be at least Ruby 2.2 since
46acd0075d80c2f886498f089fde1e9d795d50c4.

I think it's better to explicitly fail early as soon as BASERUBY
is used in this case, versus trying to debug later failures.

This modifies things to check both implicitly use of ruby in the
PATH as BASERUBY, and explicitly specified older versions of ruby
when using --with-baseruby.

Fixes [Bug #16668]
