selinux: fix avc audit messages

commit a2c513835bb6c6 ("selinux: inline some AVC functions used only once")
introduced usage of audit_log_string() in place of audit_log_format()
for fixed strings.  However, audit_log_string() quotes the string.
This breaks the avc audit message format and userspace audit parsers.
Switch back to using audit_log_format().
