modules: fall back to load from versioning /var/run directory

On upgrades the old .so files usually are replaced. But on the other
hand since a qemu process represents a guest instance it is usually kept

That makes late addition of dynamic features e.g. hot-attach of a ceph
disk fail by trying to load a new version of e.f. block-rbd.so into an
old still runnign binary.

Add a versioned directory in the temporary /var/run that qemu can look
into as well providing qemu packages a way to store modules of an
uninstalled/upgraded qemu until the next reboot.
