qcow2: use external virtual timers
Regular virtual timers are used to emulate timings related to vCPU and peripheral states. QCOW2 uses timers to clean the cache. These timers should have external flag. In the opposite case they affect the execution and it can't be recorded and replayed. This patch adds external flag to the timer for qcow2 cache clean.
