Subject: [rubygems/rubygems] Suppress warnings coming from `jar-dependencies`

This is a default gem on jruby, which ships with a rubygems plugin,
which prints warnings all over the place during our tests.

This plugin is unnecessary from our tests, so I disable it through the
`JARS_SKIP` environment variable provided by this gem.
