tests/qemu-iotests: adding savevm/loadvm with postcopy flag test

This patch implements a test case for the scenario that was failing
prior to the patch "migration/ram.c: do not set 'postcopy_running' in
POSTCOPY_INCOMING_END", commit acab30b85d.

This new test file 201 was derived from the test file 181 authored
by Kevin Wolf.
