Disables systemd-timesync *after* apt-get complete

Moves the disabling of systemd services to after all apt operations have
completed, as in theory possible that subsequent apt-get installation
operations could re-enable the systemd-timesyncd service.

There is no evidence of this occurring, but still appropriate as a risk
reduction measure.
