Change initialization to prevent crash, NEMO#604

Move init_kernel_notification() to happen before
init_first_boot_hwclock_time_adjustment_check().

If the file /var/cache/timed/first-boot-hwclock.dat
is missing, then timed tries to set the system time in
init_first_boot_hwclock_time_adjustment_check().

The function tries to stop kernel time change
monitoring, which caused timed to segfault as
the object responsible for monitoring time change
was created in init_kernel_notification(), which
was called after
init_first_boot_hwclock_time_adjustment_check().
