Bug description:
  [Impact]
  libguestfs cannot configure network on Bionic onward.

  This bug is a combination of libguestfs/supermin package and
  /etc/dhcp/dhclient-enter-hooks.d/resolved script from systemd,
  present on Bionic onward.
  When supermin creates the appliance does chroot and executes its init script.
  If networking is enabled init will call dhclient sript to configure the network.

  On Bionic onward the make_resolv_conf function of dhclient_script is overwritten
  in /etc/dhcp/dhclient-eneter-hooks.d/resolved which before exiting restarts
  the systemd.resolved service.
  However, this happening in chroot environment fails with
  "System has not been booted with systemd as init system (PID 1). Can't operate."
  and network is left unconfigured.

  [Test Case]

  $ sudo guestfish -a xenial-server-cloudimg-amd64-disk1.img --network -v << EOF
  run
  mount /dev/sda1 /
  command 'apt update'
  EOF

  libguestfs: launch: program=guestfish
  libguestfs: launch: version=1.36.13
  libguestfs: launch: backend registered: unix
  libguestfs: launch: backend registered: uml
  libguestfs: launch: backend registered: libvirt
  ...

  supermin: chroot

  ...

  + dhclient eth0
  System has not been booted with systemd as init system (PID 1). Can't operate.

  [Regression Potential]

  Minimal. The fix removes the /etc/dhcp/dhclient-eneter-hooks.d/resolved hook installed by systemd.
  systemd is not used inside the appliance so it should not cause any regression.

  Workaround

  1) Assume that libguestfs is installed, if not :
  $ sudo apt-get install libguestfs-tools

  2) Move the base.tar.gz to a temp dir, extract and remove tarball
  $ sudo mv /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/base.tar.gz ~/tempdir/
  $ cd ~/tempdir
  $ sudo tar -xzvf base.tar.gz
  $ sudo rm base.tar.gz

  3) Remove the etc/dhcp/dhclient-enter-hooks.d/resolved file
  $ sudo rm etc/dhcp/dhclient-enter-hooks.d/resolved

  4) Create tarball again
  $ sudo tar -czvf base.tar.gz etc

  5) Move it back to installation dir
  $ sudo mv base.tar.gz /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/

  6) Clean cache
  $ sudo rm -rf /var/tmp/.guestfs*
