deb pkgs: restart after upgrade TAR-1285

[andrewhsu]

Based on how I see the script to be used: https://git.launchpad.net/ubuntu/+source/init-system-helpers/tree/script/dh_systemd_start?h=ubuntu/xenial

Related man page from xenial docs: http://manpages.ubuntu.com/manpages/disco/en/man1/dh_installsystemd.1.html

To address TAR-1285
