sys: add new log message for kernel status reset after leap second

Browse Source 
When a leap second is applied by the kernel, it doesn't actually clear
the STA_INS|STA_DEL bits from the status word, but the state returned
by ntp_adjtime()/adjtimex() is TIME_WAIT until the application clears
the bits.

Add "System clock status reset after leap second" log message for this
case.
