debian: Don't create/remove groups during upgrades/downgrades

The debian maintainer scripts remove and create group during upgrades
and downgrades, causing the group ids to change, locking users out of
/var/lib/toolbox.

This commit modifies the debian maintainer scripts so that they only
remove groups during package removals.
