boot - Bring in fix for qemu menu time bug

* qemu does not debounce the RTC data.  The RTC chip uses a serial interface
  as well as a simple carry propagation incremenber which can catch
  transitions in the middle of an update, resulting in corrupted data.

* Simply requery the time until a stable value is found.
