[pve-devel] [RFC PATCH v2] 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 'configure' step.

Our other packages are doing this manually, or automatically
when the dh_systemd_enable helpers generated a postinst,
but this was missing here.
---
 changes since V1:
 * move the unmasking in the configure step, since this is the parameter
  called on install
