[meta-selinux][PATCH] audit: fix host contamination for swig

["Yi Zhao" <yi.zhao@windriver.com>]

The audit build uses swig to generate a python wrapper. But there is a
hardcoded include directory in auditswig.i, which causes header files on
the host to be used when building. This will cause build error on some
old systems. e.g. on CentOS7 with buildtools:
  audit_wrap.c: In function '_wrap_audit_rule_flags_set':
  audit_wrap.c:5018:19: error: dereferencing pointer to incomplete type 'struct audit_rule'
  5018  if (arg1) (arg1)->flags = arg2;
        ^~

+Subject: [PATCH] audit: Fixed swig host contamination issue
+
+The audit build uses swig to generate a python wrapper.
+Unfortunately, the swig info file references host include
+directories.  Some of these were previously noticed and
+eliminated, but the one fixed here was not.
