apparmor: use SEND_SIG_NOINFO instead of NULL in aa_audit()

Browse Source 
SEND_SIG_NOINFO is defined as ((struct kernel_siginfo *) 0), so passing
NULL works, but:

- this works "by accident" and looks as if the caller doesn't understand
  the signal sending API.

- more importantly, this hides the usage of SEND_SIG_NOINFO from grep,
  and this is really bad.
