audit: move kaudit thread start from auditd registration to kaudit in…

…it (#2) Richard made this change some time ago but Eric backed it out because the rest of the supporting code wasn't ready. In order to move the netlink multicast send to kauditd_thread we need to ensure the kauditd_thread is always running, so restore commit 6ff5e45 ("audit: move kaudit thread start from auditd registration to kaudit init").
