Exclude :release group from integration test bundle install

The :release group contains github_changelog_generator (via a GitHub
fork) which has an unresolvable rainbow dependency. Since release
tooling is never needed during test runs, excluding it unblocks bundle
install and allows the syslog gem to be installed — which Puppet's POSIX
feature check requires to load successfully.
