Pull up following revision(s) (requested by riastradh in ticket #1053):

        sys/secmodel/securelevel/secmodel_securelevel.c: revision 1.36

Accept ioctl(RNDADDDATA) estimates at securelevel 1 (but not 2).
securelevel=1 is supposed to be a reasonable default for normal
computers.  This got in the way of ever getting entropy from a seed
on a machine with no HWRNG -- e.g., from another machine, or by
making the executive decision that what has been sampled is good
enough and issuing `head -c 32 < /dev/urandom > /dev/random'.
