test: silence SC2329 for indirectly invoked cleanup() functions

shellcheck 0.10+ reports SC2329 ("This function is never invoked") for
the per-testcase cleanup() functions in TEST-75-RESOLVED.sh, which are
only invoked indirectly via trap. The existing SC2317 markers don't
cover it, and inserting a new testcase shuffles which definitions the
heuristic fires on, making pre-existing findings show up as new in
differential CI runs. Extend the markers to SC2317,SC2329, matching
what testcase_dot_strict_per_link_verify() in this file and other test
units already do.
