Pull up following revision(s) (requested by riastradh in ticket #882):

        etc/rc.d/random_seed: revision 1.9

Don't delete the random seed before issuing `rndctl -S'.
`rndctl -S' can replace the file just fine, and deleting it ahead of
time adds a window during which we can lose the seed altogether if
the system is interrupted by a crash or power outage.
