fork: Explicitly set PF_KTHREAD

Browse source

Instead of implicitly inheriting PF_KTHREAD from the parent process
examine arguments in kernel_clone_args to see if PF_KTHREAD should be
set.  This makes knowledge of which new threads are kernel threads
explicit.

This also makes it so that init and the user mode helper processes
no longer have PF_KTHREAD set.
