initramfs: sync time with NTP 

Using the Busybox NTP client, we can set the system clock in early
userspace.  This will ensure the system clock is correct before
anything, even systemd, is started from the real rootfs.

Obviously, this requires the DHCP server to specify NTP server addresses
in the client lease.
