debian: Update packaging source from Debian/Ubuntu.

* Update upstream OVS debian packaging to be on par with package
  source in Debian/Ubuntu:
  - Provide a openvswitch-switch-dpdk package that integrates with
    the dpdk package in the distributions so that end users can opt
    into a DPDK-enabled Open vSwitch binary.
  - Provide systemd service files.
  - Provide openvswitch-source package for reproducible integrated
    build of for example OVN.
  - Stop building shared library and subsequently remove
    libopenvswitch and libopenvswitch-dev binary packages.
