Title: Fix for JRUBY-6666, Open3.popen3 handling for arrays in arg list

This patch adds a fix for [JRUBY-6666](http://jira.codehaus.org/browse/JRUBY-6666), a bug in the handling of Open3.popen3(). This method should accept a two-element array giving path and argv[0] as the first item in the argument list, as on MRI.

I have submitted a corresponding [test case](https://github.com/rubyspec/rubyspec/pull/137) to RubySpec.
