[pve-devel] [RFC PATCH] Fix #1446: allow pve-firewall package install twice in a row

[Emmanuel Kasper]

On packages removal (!= purge) systemd units are masked.
The postinst script has then to reenable this units at the
beginning of the script.

Our other packages are doing this manually, or automatically
when the dh_systemd_enable helpers generated a postinst,
but this was missing here.
