Bug description:

  dhclient fails to notify resolved about DNS servers due to bash-
  specific redirect inside 'resolved' hook script

  [test case]

  see original description below

  [regression potential]

  any regression would likely cause resolved not to be aware of
  dhclient-provided dns servers

  [other info]

  This is needed only in Eoan and later; X/B/D do not have the bash-
  specific redirect '&>' in their hook file.

  original description:

  The file /etc/dhcp/dhclient-enter-hooks.d/resolved
  provided by systemd (242-7ubuntu3) causes the dhclient failing to get DNS due 
to systemd-resolved is not run.
  This issue can be reproduced on Ubuntu Eoan:

  Attached please find the patch for this. The output for md5sum in the
  hook file resolv should separate the stdout and stderr so it won't
  compare the wrong data.
