Subject: [rubygems/rubygems] Allow upcoming JRuby to pass keywords for
 Kernel#warn

jruby-head (which will be JRuby 9.4.0.0) can now properly process
the keywords to Kernel#warn.  I cannot think of any capability based
test for this so I constrained it using a version guard.  Only JRuby
will ever hit the version guard.
