Do not run gnome-initial-setup during OEM preparation stage

[Jean-Baptiste Lallement]

During an OEM installation, gnome-initial-setup must not run in OEM preparation mode. Besides it asks question that are not relevant to this mode like the user name and the password.

There are several ways to determine if we are running an OEM session:
- Current user is 'oem'
- It is set to log in automatocally
- /home/oem/Desktop/oem-config-prepare-gtk.desktop exists

I suspect fixing bug #1765644 would fix this too.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubiquity - 18.04.10

---------------
ubiquity (18.04.10) bionic; urgency=medium

  [ Colin Watson ]
  * Update translations from Launchpad.

  [ Simon Quigley ]
  * Following the lead of the GTK frontend, remove the encrypted home
    directory option from the Qt installer since ecryptfs no longer has
    support from the Ubuntu Security Team. This removes the frontend but keeps
    the codebase for the option so it can be added back later using another
    technology (LP: #1761396).

  [ Adam Conrad ]
  * Automatic update of included source packages: localechooser
    2.71ubuntu2.

  [ Jean-Baptiste Lallement ]
  * Do not start gnome-initial-setup for the OEM user (LP: #1765651)
