Title: versionize vm:test

In the course of fixing some tests only surfacing under 1.9, I thought it'd be useful to be able to run `vm:test` in different versions side-by-side.

Previously, even if `--default-version=19` is used, `vm:test` is run in 1.8 mode, not in 1.9, when building rubinius with just the `rake` command. This situation is also fixed.

As `ci` is run under 1.8 and 1.9 mode when buidling, `vm:test` is now run under 1.8 and 1.9 mode too.

So here is the patch!

Thanks for reviewing :) Any comments are greatly appreciated.
