refactor(role): Rename role to better reflect non-VM use cases

Without an [options] or similar INI header line pacman config files
in '/etc/pacman.d' can sometimes load incorrectly, for example when
multiple files exist where some of them do and other do not have the
header. We're normalizing our config file here so that it no longer
trips up pacman.
