Bug#1088566: xdg-utils: xdg-open does not support KDE version 6

[Julien Bigot]

Package: xdg-utils
Version: 1.1.3-4.1
Severity: important
X-Debbugs-Cc: julien at julien-bigot.fr

Dear Maintainer,

When KDE_SESSION_VERSION is sit to 6, as in the latest release in sid, xdg-open
has no behaviour selected. The `case "${KDE_SESSION_VERSION}" in` in `open_kde`
function lacks an option for 6, and ends up in the default option that is to do
nothing.

In addition, KDE6 in debian currently ships with kde-open & kde-open5, but not
kde-open6, (see bug #1088541 in kde-cli-tools) so as of now the best option
would be to reuse the case for KDE4, adding a `|6` there to get:
```
        4|6)
          kde-open "$1"
        ;;
```

Best,
Julien
