[OE-core] [PATCH 1/4] masterimage.py: fix issue with calling reboot on masterimage/DUT

[Erik Botö]

I guess an introduction should have been added to this patchset, so here 
it comes a bit late:

These patches are what I needed to do in order to get automated runtime 
tests on target using the systemd-boot target working. There is an open 
bug in the bugzilla for this as well: 
https://bugzilla.yoctoproject.org/show_bug.cgi?id=11524.

Cheers,
Erik
