ruby: use superenv

env :std was added to this formula without a comment as to why it is
needed, and there appears to be nothing on the issue tracker. Having
used a superenv-built ruby without issue for a few days I am assuming it
was a mistake.

If it causes problems we can either fix them or re-add env :std with
appropriate documentation.
