fork: Add kernel_clone_args flag to ignore signals
Since: commit 10ab825bdef8 ("change kernel threads to ignore signals instead of blocking them") kthreads have been ignoring signals by default, and the vhost layer has never had a need to change that. This patch adds an option flag, USER_WORKER_SIG_IGN, handled in copy_process() after copy_sighand() and copy_signals() so vhost_tasks added in the next patches can continue to ignore singals.
