kf6 vs. kf5 conflict report

[Harald Sitter]

with kf6 progressing nicely here's a first conflict report of files
that appear in both kf6 and kf5 under the same name. this largely
affects translations and docs it seems. this list may not be entirely
comprehensive, I've only thrown together a script in a couple minutes.

one question is whether ECM should be co-installable, not sure if that
has been discussed

report for /usr:
https://collaborate.kde.org/s/3gz2KfoGLsS4TF5

furthermore the following files outside /usr clash between kf6 and 5:
'/etc/xdg/accept-languages.codes'
'/etc/xdg/kshorturifilterrc'
'/etc/xdg/autostart/baloo_file.desktop'
'/lib/udev/rules.d/61-kde-bluetooth-rfkill.rules'
