LanguageModuleRequirement: remove rbx support

This test wasn't running by default, so we missed that it wasn't
actually being executed - or that it was failing when running in the
testing environment.

As far as I can tell this is not, and has not, been used either in core
or in any tap, third party or otherwise, so just remove the feature and
its test.
