  AUDIT_USER_AVC messages are not printk'ed when auditd is not running

Bug description:
  The auditd daemon is not part of the default phone images. At the
  kernel level, the audit_enabled variable remains 0 until an auditd
  daemon registers itself. There is a bug in old kernels that causes
  AUDIT_USER_AVC messages to be ignored when audit_enabled is 0. I fixed
  the bug several years ago and marked the patch for the stable tree but
  the phone kernels (mako, at least) did not pull in the patch. The
  upstream commit id is:

    0868a5e150bc4c47e7a003367cd755811eb41e0b

  What this means for our phone images is that any denial messages from
  the system D-Bus daemon are dropped instead of being properly routed
  to the syslog. This results in headaches for debugging app confinement
  denials.
