SELinux: use new audit hooks, remove redundant exports
Setup the new Audit LSM hooks for SELinux.
Remove the now redundant exported SELinux Audit interface.
Audit: Export 'audit_krule' and 'audit_field' to the public
since their internals are needed by the implementation of the
new LSM hook 'audit_rule_known'.
