Valgrind and existing test cases are a heck of a thing.

Would be nice to hook up an automated target that integrates valgrind
into libapparmor's make check, at least optionally. Also, generating
coverage information would be useful, too.

Even with this fix, there are a few testcases that valgrind reports
leaks; they're specifically cases that are invalid parse records. I
have not tracked down exactly what's going wrong there.
