By default, qemu user's home dir points to '/' which shouldn't be used
at all. We therefore pass the HOME variable from the current variable
iff not running as SUID, which means that for systemd we never set it.
This patch makes sure, that for system QEMU this is always set to
libDir/<driver>, session mode is left untouched.

For session mode, only XDG_CACHE_HOME is set, because we want to remain
integrating with services in user session, but for system mode, this
would have become reading/writing to '/' which carries the obvious issue
with permissions (also, '/' is the wrong location in 99.9% cases anyway).

Depending on whether QEMU actually supports the option, we can put the
'rendernode' on the '-display egl-headless' cmdline.

Since QEMU 2.12, QEMU understands a new vfio-pci device option 'display'
which can be used to turn on display capabilities on vgpu-enabled
mediated devices, IOW emulated GPU devices like QXL will no longer be
needed with vgpu-enable mdevs.
QEMU defaults to 'auto' for the 'display' attribute, which is not
foolproof, so we need to play it safe here and default to display='off'
if this attribute wasn't provided in the XML explicitly.
