Enabling first-boot-set-hostname service on witherspoon

first-boot-set-hostname service will set a unique hostname
to the machine on the very first boot. The idea of this
commit is to enable this service as a part of witherspoon
image.

Tested by:

1. Enable first-boot-set-hostname.service
   - systemctl enable first-boot-set-hostname.service

2. Reboot the machine
   - reboot

Post reboot, hostname will be changed to hostname-serialno
