M9.R.15q.5.5: kidletime disable both Wayland and X11 backends

kidletime 6.10.0's WITH_WAYLAND=ON path pulls in
``find_package(Qt6WaylandClient REQUIRED CONFIG)`` +
``find_package(PlasmaWaylandProtocols REQUIRED)``. Neither has a
from-source sibling recipe yet (qt6-wayland is the blocker;
plasma-wayland-protocols would follow). With BOTH WITH_X11=OFF +
WITH_WAYLAND=OFF the library compiles a stub (idleTime() = 0) but
keeps the public API + SONAME intact, so kwin's idle-management
plugin links successfully. The v1 deliverable doesn't need the
runtime idle-detection backend wired up yet.
