Script to update sysinv/motd in upgrade

After upgrade, the system name was no longer
displayed in motd after ssh into central controller.

Test plan
  PASS: Simplex upgrade to Debian successfully
        and verify that system name displays
        correctly when logging in via ssh
  PASS: Duplex upgrade to Debian successfully
        and verify that system name displays
        correctly when logging in via ssh
  PASS: Test script in DC subcloud upgrade successfully
