This value needs to be set to actual static max for qmemman to work properly. If it's set higher than real static-max, qmemman will try to assign more memory to dom0, which dom0 could not use - will be wasted. Since this script is executed before any VM is started, simply take the current dom0 memory usage, instead of parsing dom0_mem Xen argument. There doesn't seem to be nice API to get this value from Xen directly. Fixes QubesOS/qubes-issues#4891
