test: use modern qemu numa arguments

test: use modern qemu numa arguments

Upgrading to qemu 5.2 breaks TEST-36-NUMAPOLICY like:
  qemu-system-x86_64: total memory for NUMA nodes (0x0) should
  equal RAM size (0x20000000)

Use the new (as in >=2014) form of memdev in test 36:
 -object memory-backend-ram,id=mem0,size=512M -numa node,memdev=mem0,nodeid=0

Since some target systems are as old as qemu 1.5.3 (CentOS7) but the new
kind to specify was added in qemu 2.1 this needs to add version parsing and
add the argument only when qemu is >=5.2.

Fixes #17986.
