mc146818rtc: add "rtc-time" link to "/machine/rtc" 



Add a link to rtc under /machine providing a stable
location for management apps to query the value of the
time.  The link should be added by any object that sends
RTC_TIME_CHANGE events.

{"execute":"qom-get","arguments":{"path":"/machine","property":"rtc-time"} }

Suggested by Paolo Bonzini and Andreas Faerber.
