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.
Fixes: c9e6189fb03123a7 ("ntp: Make the RTC synchronization more reliable")
