Title: (maint) Use PL Gem mirror in acceptance tests

The testing infrastucture should be resilient to network issues. For
acceptance tests that exercise the Gem provider and setup that installs
Gems, there hasn't been a clean way to specify that the internal mirror
should be used. This follows the Gemfile pattern and selects the
internal mirror if it's available.
