Bug#1102123: libsdl2-2.0-0: Unable to create OpenGL context >= 3.0

[Pas Pab]

Just to confirm that the issue was not caused by the upgrade of SDL,
it was a permissions thing.

I run qemu once with sudo and this must have changed some permission
that only allowed root access from then on. Launching a VM with
virt-manager/libvirt fixes it and let me run again as normal user.
