        sys/kern/subr_cprng.c: revision 1.37 (via patch, adapted)

Make kern.arandom truncate the output instead of failing with ETOOBIG
when the requested data exceeds 256 bytes in size. The actual size of
the returned data is output to oldlenp.

This matches FreeBSD's behaviour and seems to be more in line with
what software in the wild expects.
