pkgtools/pkglint: update to 23.2.2

Changes since 23.2.1:

Do not wrongly warn when adding a tool that is only available on
${OPSYS} to CONFIGURE_ENV.${OPSYS}.

Use proper capitalization for 'makefile' in a few places, when referring
to the general file format instead of a file named exactly 'Makefile'.
