    Replace chronyc "waitsync" with "makestep"

    Prior to this patch we had the "chrony waitsync" command with a
    hardcoded timeout of "20". Sometimes that wasn't enough when deploying
    on some slower machines in my experience [0].

    This patch is changing the "waitsync" command to "makestep", that way
    we tell chronyd to make the system clock correct immediately (instead
    of gradually correcting the time). It should be fine for our usecase
    because these are ran during the deployment.
