kde: add Python3 + LibMount + kfilesystemtype + QVariant include fixes for KF6 6.26.0 on Redox

- kf6-kguiaddons: add -DBUILD_PYTHON_BINDINGS=OFF (Shiboken6 unavailable on Redox)
- kf6-kcoreaddons: stub kfilesystemtype.cpp (Redox+CMAKE_SYSTEM_NAME=Linux
  collides with public function; relibc lacks statfs magic numbers);
  disable LibMount and BUILD_PYTHON_BINDINGS
- kf6-kcolorscheme: add missing <QVariant> include in kcolorschemehelpers_p.h

All 19 Qt 6.11.0 + KF6 6.26.0 packages now build clean on redbear-full baseline.
