[Buildroot] [PATCH 3/3] ruby: remove rubygems

[Gustavo Zacarias]

It's currently in a non-working state since it requires a couple of
extensions that don't build at the moment (they try to execute tests in
configure) and also requires a target compiler.
So remove it to avoid false expectations and reclaim target space back
of about 1.5 MiB.
