util/lint: update checkpatch & spelling.txt to upstream versions

- Update checkpatch.pl to version 0547fa58
(checkpatch: add 6 missing types to --list-types)
- Update spelling.txt to version d9f91f8
(scripts/spelling.txt: add a bunch more spelling mistakes)
- Fix an additional unescaped left brace in a regex - causes warnings
in new versions of perl.
