user/3104: Propolice katch kauth. (Patches and testcase).

[Jan Johansson <janj+openbsd_(_at_)_wenf_(_dot_)_org>]

On i386 it works because the heap is dirty, on sparc64 it
dosen't work because the heap is clean and loop goes on
forever.

Patch to fix this.

This fixes the test case on i386, and reveals another bug on
sparc64.

Testcase:

#include <stdlib.h>

/* Fixed in NetBSD */
/* /usr/src/lib/libc/stdlib/random.c:1.20 */

int
main(int argc, char **argv)
{
    int len = atoi(argv[1]);
    char *foo = malloc(len);
    char *oldfoo;

    oldfoo = initstate(time(NULL), foo, len);

    return 0;
}
