Merge ~paelzer/ubuntu/+source/qemu:lp-1830243-secure-boot-toleration-xenial into ubuntu/+source/qemu:ubuntu/xenial-devel

PPA: https://launchpad.net/~paelzer/+archive/ubuntu/bug-1830243-secure-boot-toleration

Testign this needs a secure boot enabled s390x kernel which I haven't seen yet.
I asked on the bug who could verify this.

I would like to review this one, since these were already in qemu 4.0 merge. Will get back to this soon.

I don't have access to s390 yet (working on it) so I'll do a logical review only.
