Log message:
kernel: remove global "randompid" toggle
Apparently, we used to created several kthreads before the kernel
random number generator was up and running. A toggle, "randompid",
was needed to tell allocpid() whether it made sense to attempt to
allocate random PIDs.
However, these days we get e.g. arc4random(9) into a working state
before any kthreads are spawned, so the toggle is no longer needed.
