Fix facter binary conflict when installing puppet-strings

The previous fix (user_install: false) correctly moved the puppet-strings
gem install into the puppetlabs gem path to avoid a load path conflict.
However, puppet-strings 5.0.0 depends on puppet, which depends on facter,
and the facter gem tries to install a binary to /opt/puppetlabs/puppet/bin/facter
that already exists from the puppet-agent package.

Adding force: true allows gem to overwrite the conflicting binary. This is
safe because the facter gem and puppet-agent's facter are compatible.
