Introduce sysctl_securelevel() to modify `securelevel' mp-safe. Keep
KERN_SECURELVL locked until existing `securelevel' checks became moved
out of kernel lock.

Make sysctl_securelevel_int() mp-safe by using atomic_load_int(9) to
unlocked read-only access for `securelevel'.

Unlock KERN_ALLOWDT. `allowdt' is the atomically accessed integer used
only once in dtopen().
