Merge lp:~xnox/ubiquity/fix-oem-user into lp:ubiquity

[Dimitri John Ledkov]

[Dimitri John Ledkov (xnox)]

* dbus-launch --exit-with session leaves around defunct dbus-launch processes after exiting with session. Later userdel complains that it cannot remove user used by that process. There are no other processes by oem user left, hence using killall -u oem || true, before removing the user. I've tried tracking the pid imperically from the PID that dbus-launch prints on stdout, but that's not the pid that is left around hanging. Not sure if there are any better ways to kill that stray dbus. I guess for T-series we should look into why dbus-launch is leaving defunct process around.

I'd prefer using pkill rather than killall on general principles, but this adjustment to my change looks fine to me.

review: Approve

Use pkill instead, and depend on it
