bug(engine): kics throws an error and closes when scanning a invalid symbolic link directly

[saars-orca]

Expected Behavior

KICS should print out a warning and skip the file if it does not exist/points to a non-existing file.

Actual Behavior

When scanning a symbolic link that points to a non-existing file, kics returns an error and closes instead of skipping the file.
