ntp: Fix RTC synchronization on 32-bit platforms
Due to an integer overflow, RTC synchronization now happens every 2s instead of the intended 11 minutes. Fix this by forcing 64-bit arithmetic for the sync period calculation. Annotate the other place which multiplies seconds for consistency as well.
