hwclock.sh had default update-rc parameters which made it run after
other tasks that work with the clock such as connman. This causes a
time obtained by NTP to be clobbered by a potentially incorrect time
in the RTC.
Provide non-default INITSCRIPT_PARAMS to have hwclock.sh run during
the rc startup before runlevel initscripts start.
