Subject: [rubygems/rubygems] Remove explicit `psych` activation

We don't need to explictly activate `psych` since `require` will take
care of that automatically.

We don't need to care about a minimum version either since the oldest
ruby we support at the moment ships with a `psych` version higher than
2.0.0.
