um: rtc: use RTC time when calculating the alarm
The kernel realtime and the current RTC time may have a (small) offset.
Should the kernel time be slightly in the future, then the timeout is
zero. This is problematic in time-travel mode, as a zero timeout can be
correctly configured and time never advances.
Replace the kernel realtime read with a read of the actual persistent
RTC clock. Also, for time-travel, calculate the exact nanoseconds needed
for the clock to advance.
