[qt-kit] `dev-qt/qtwaland` needs to depend on `dev-qt/qtgui[wayland]`

[cuantar]

ERROR: Qt Gui has been built without 'wayland' feature. This feature is required for building Qt Wayland Client.

CMake Error at /usr/lib64/cmake/Qt6/QtBuildInformation.cmake:220 (message):
  Check the configuration messages for an error that has occurred.
Call Stack (most recent call first):

  CMakeLists.txt:49 (qt_build_repo)

The USE flag for wayland should probably required here in the deps, so that the user is warned about it during dependency resolution instead of seeing a cmake failure.

@cuantar i think that here the problem is related to the mix qt6 and qt5. qt-gui is available only for SLOT 5.

Maybe, @linuxexplorer can integrate an additional comment about this issue.

@cuantar what flags do you have for qtbase? Is it installed with gui and wayland flags enabled?
