This update for sshuttle fixes the following issues:

- Remove the systemd protection settings:

  * PrivateDevices=true
  * ProtectHostname=true
  * ProtectClock=true
  * ProtectKernelTunables=true
  * ProtectKernelModules=true
  * ProtectKernelLogs=true
  * RestrictRealtime=true

from service file as they imply NNP, which doesn't work
with the sudo setup sshuttle uses (boo#1212949)
