[pve-devel] [PATCH proxmox-ve] apt hook: disable on remove

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

and (re-)enable on install. adapted from apt-listbugs/apt-listchanges, which
solve the issue of removing (instead of purging) the package keeping the
conffile while removing the hook binary in the same fashion.
