hooks: fix pre-commit sbolint never running

The sbolint loop extracted build dirs with "cut -d/ -f1,2", which is
correct for SBo's own <category>/<package>/ layout but yields a file
path in this repo's flat <package>/ layout (e.g. nuclei/nuclei.info).
The guard then tested nuclei/nuclei.info/slack-desc, which never
exists, so sbolint was silently skipped on every package commit.

Walk up from each changed file to the directory holding the
.SlackBuild instead. Depth is no longer assumed, so this works for
the current flat layout and for <category>/<package>/ after the
planned migration.
