abort in srandomdev if kern.arandom sysctl fails

The sysctl cannot fail. If it does fail on some FreeBSD derivative or
after some future change, just abort() so that the problem will be found
and fixed.

While abort() is not normally suitable for a library, it makes sense
here.

This is akin to r306636 for arc4random.
