This remedies an issue where applications like systemsettings and
plasma-discover do not completely respect theming (e.g. when dark theme is
enabled), with the following notable error message:

kf.kirigami.platform: Failed to find a Kirigami platform plugin for style "org.kde.desktop"

* gnu/packages/kde-frameworks.scm (qqc2-desktop-style)[inputs]: Add
kcolorscheme to fix a theming issue.
[arguments]<#:tests?>: Disable failing tests introduced by adding the
kcolorscheme input.

Hi!

According to 'guix refresh --list-dependents qqc2-desktop-style', there
are 18 dependent packages.

I haven't noticed any visible regressions with this change running
Plasma, and I can confirm theming in at least systemsettings and
plasma-discover is fixed by the change.  However, adding kcolorscheme as
an input causes the check phase to fail (log included at the end).  This
appears to be due to tests that are enabled when kcolorscheme is added,
one of which fails.

The D-Bus error message is present in the current and patched
version. I've tried setting the HOME and XDG_CACHE_HOME environment
variables as it's done in other Qt/KDE packages, which has some effect
on the tests but still results in failure.  The Nix packages seem to
reveal a partially circular dependency between qqc2-desktop-style and
kirigami [1] [2]; I wonder if this is related to the issue?

Here's the check phase log:
