Subject: Use new hwclock options to speed up boot process
References: bnc441106

hwclock has new options --nowait --preadjust to allow us
calling it without waiting for a clock tick, resulting in
the system time to be set to up to 1s late (but never early!).
Use this to speed up the boot process by ~1.5s.

Run the exact calculation in the background (which will take
~2s to complete if there is a correction to be made, but will
not require significant CPU time).
