Acceptance tests: work around socket dir

Change 32558ce7a4 introduced specific directories for the socket dir
when using python/qemu/machine.py:QEMUMachine.  iotests probably
didn't catch the condition that two simultaneous QEMUMachine
instances, without manually set temporary or socket dirs would clash.

Having two QEMUMachine instances is a condition expected for many
acceptance tests, and it's already used by the migration tests.
