in bc62b6e5 dictsort was applied to the pillar entries. But in the
sudoers file *order matters* so, using `dictsort`, breaks it.
From man 5 sudoers:
> When multiple entries match for a user, they are
> applied in order. Where there are multiple matches, the last match
> is used (which is not necessarily the most specific match).
Removed `dictsort` from the {users,groups,netgroups} specifications.
BREAKING CHANGE: sudoers entries' order will change and might break
existing configuration. You should check your pillars and rendering.
