[Bug 1865015] [NEW] hostname changed after end-user setup

[Martijn Loinkje]

Public bug reported:

After installing Ubuntu 18.04.1 LTS as OEM and changed the hostname using the setup everything looks fine. 
When I'm done configuring, I select "prepare for shipping to end user" and reboot the machine. The new user fills in their info BUT it shows an options to fill in the "Device name/Computer name/hostname" which I want to be static because they are based on their system serial number. 

Info/Devicename: 
{serial code}

hostname: 
{serial code}

cat /etc/hostname
{serial code}

cat /etc/hosts 
127.0.0.1   localhost
127.0.0.1   {serial code}

Reboot + end-user-config

cat /etc/hostname
{username}-{device model}

A machine should have a static default hostname independent of the user.
If a user wants to change it, they can do it by hostnamectl.
