qemu-timer: change unix timer to dynticks

A timer that wakes up every millisecond puts a lot of stress on the
iothread.  The large amount of IPIs causes very high context switch
activity, making emulation slow and the UI unusable.  This is by the
way the same reason why the Windows timers were switched to dynticks.
