Previously, vagrant could not do everything with passwordless sudo. Eg.
`sudo -u other-user ls` would ask for a sudo password, causing tools
like ansible to hang when trying to execute commands as another user.
Rather than determining what package to install on which series, just install
them both for the time being as they don't seem to conflict in any current
series.
