Remove security profiles from sysinstall. Currently, security profile

selection is used to drive two configuration parameters:

(1) Default enable/disable for sshd
(2) Default enable/disable for securelevels

Replace this with an explicit choice to enable/disable sshd.  A
follow-up commit will add a configuration option to the Security
post-install configuration menu to set the securelevel in rc.conf
explicitly.  This should reduce the level of foot-shooting associated
with accidental enabling of securelevels, make the nature and
implications of the securelevel configuration options more explicit,
as well as make the choice to enable/disable sshd more explicit.
