Revert "Add ntpdate to ensure hwclock sync"

This reverts commit 0a6199bded.

This doesn't actually work because if ntpd is started, 
ntpdate cannot run. We would need another solution to
ensure the system clock is synced under ntp.  The ntpdate
service is a oneshot service so it just runs a single
ntpdate (and hwclock) on boot.
