Unfortunately i doubt that we could help with that. I did not look into
every software package from your list, but many of those packages did
not have compile time switch for (not)using desktop-file-utils.

If you are still needed to clean up files, that cause no harm to your
system - i can only suggest you to mask /usr/share/applications via
INSTALL_MASK(to prevent these desktop files from installing at all)
