Conrad Meyer 08a7e74c7c getentropy(3): Fallback to kern.arandom sysctl on older kernels 
On older kernels, when userspace program disables SIGSYS, catch ENOSYS and
emulate getrandom(2) syscall with the kern.arandom sysctl (via existing
arc4_sysctl wrapper).

Special care is taken to faithfully emulate EFAULT on NULL pointers, because
sysctl(3) as used by kern.arandom ignores NULL oldp.  (This was caught by
getentropy(3) ATF tests.)
