parser: dirtest that was supposed to be part of the previous commit

libapparmor: fix handling of failed symlink traversal, fixed a couple
of directory walk issues that could cause failures. The test included
in this commit was supposed to be included in the previous commit,
but was accidentally dropped. Even worse the make file changes did
make it causing the previous commit to break the CI.

Fixes: MR: https://gitlab.com/apparmor/apparmor/-/merge_requests/85
