tools: run check-coccinelle.sh with (updated) parsing_hacks.h

This commit runs the check-coccinelle checker scripts with the
parsing_hacks.h. Because this was missing before there were some
issues that did not get flagged.

While at it it also adds some missing cleanup attributes and
iterators to get better results. Its a bit sad that there is no
(easy/obvious) way to detect when new things are needed for
parsing_hacks.h
