Stop deleting system user/group on remove/purge

Removing system users/groups on purge is considered bad practice,
as the kernel recycles UIDs/GIDs. So any potential leftover
file/directory can then become owned by the next user/group that
gets added, with unpredictable consequences.

Install and use sysusers.d/tmpfiles.d config files

sysusers.d/tmpfiles.d config files allow a package to use declarative
configuration instead of manually written maintainer scripts.
This also allows image-based systems to be created with /usr/ only, and
also allows for factory resetting a system and recreating /etc/ on boot.
