Bug description:
  Since libvirt-daemon-log-hwe have the same dynamic conffiles (systemd
  links, apparmor local) than libvirt-daemon-log

  When libvirt-daemon-log-hwe is installed, purging libvirt-daemon-log
  might break libvirt-daemon-log-hwe by removing the systemd unit links
  (/etc/systemd/system/** -> /usr/lib/).

  Other packages are also affected, for example libvirt-daemon.

  Here are the purge actions done by dh-* for libvirt-daemon in the
  postrm maintscript:

  ...
  update-rc.d libvirtd remove
  deb-systemd-helper purge 'libvirtd-admin.socket' 'libvirtd-ro.socket' 'libvirtd.socket'
  deb-systemd-helper purge 'libvirtd.service' >/dev/null

  rm -f "/etc/apparmor.d/disable/usr.sbin.libvirtd" || true
  rm -f "/etc/apparmor.d/force-complain/usr.sbin.libvirtd" || true
  rm -f "/etc/apparmor.d/local/usr.sbin.libvirtd" || true
  rm -f /var/cache/apparmor/*/"usr.sbin.libvirtd" || true
  rmdir /etc/apparmor.d/disable 2>/dev/null || true
  rmdir /etc/apparmor.d/local   2>/dev/null || true
  rmdir /etc/apparmor.d         2>/dev/null || true

  Steps to reproduce
  ---

  $ apt install libvirt-daemon-log
  $ apt install libvirt-daemon-log-hwe
  $ apt purge libvirt-daemon-log

  $ systemci status virtlogd
  ● virtlogd.service - libvirt logging daemon
       Loaded: loaded (/usr/lib/systemd/system/virtlogd.service; disabled; preset: enabled)
