softmmu/runstate.c: add RunStateTransition support form COLO to PRELAUNCH
If the checkpoint occurs when the guest finishes restarting but has not started running, the runstate_set() may reject the transition from COLO to PRELAUNCH with the crash log: {"timestamp": {"seconds": 1593484591, "microseconds": 26605},\ "event": "RESET", "data": {"guest": true, "reason": "guest-reset"}} qemu-system-x86_64: invalid runstate transition: 'colo' -> 'prelaunch' Long-term testing says that it's pretty safe.
