Fixes #2983.

Note that Ruby 1.9 has no support for environment-driven proxy
settings, so this change is only available in 2.0 mode on JRuby
1.7.

JRuby comes with rake as part of its ruby stdlib. rake has a feature
to spawn a new ruby process and execute things. this is used by unit
tests and rspec. this spawn needs to determin the ruby executable. when
jruby runs from the jruby-complete.jar then ENV['RUBY'] will tell rake to
use which does actual execute and spawn a new
`java -cp jruby-complete.jar org.jruby.Main` process.

added an integration test in maven/jruby-complete/src/it which executes
`java -jar jruby-complete.jar -S rake test:mri`

there are still short comings with ArgumentProcessor and some -J-xyz switches

…should do the same

first the code need to launch a new jruby process, when the current
directory is inside the classloader then the spawned jruby process
needs to have the same current directory
