kde: fix kf6-kcmutils build + declare kde-cli-tools KCM/Parts deps

kf6-kcmutils: (1) add the missing 'source local/scripts/lib/qt-sysroot.sh' before
redbear_qt_link_sysroot_dirs (undefined-function crash); (2) drop Qt6::Test from
the REQUIRED components (qtbase FEATURE_testlib=OFF, tests off); (3) declare the
kirigami dependency so its org.kde.kirigami QML module is in the sysroot (an
ecm_find_qmlmodule REQUIRED check).

kde-cli-tools: declare kf6-kcmutils + kf6-parts deps (find_package(KF6 REQUIRED
COMPONENTS KCMUtils Parts)); add -DBUILD_DOC=OFF (the doc subdir hard-requires
KF6DocTools + the docbook/xsltproc toolchain, not needed for a working desktop).
