This patch fixes the ordering of UTMP events. The first event that is
expected in /var/run/utmp is reboot, next is the runlevel change to
the configured runlevel, e.g. from S --> 2.
Let the bootmisc plugin handle this, it knows when /var/run/utmp has
been created and is writable. It is not the eact boot time, but close
enough for most usees.
