gnu: qbittorrent{,-nox}: Use qt-build-system.

CMake is now upstream’s preferred build system.

* gnu/packages/bittorrent.scm (qbittorrent)[build-system]: Use qt-build-system.
[arguments]: Drop custom wrap phase. (Re-)enable tests.
[inputs]: Remove input labels. Drop qtbase-5.
[native-inputs]: Drop pkg-config.
(qbittorrent-nox)[arguments]: Adjust configure-flags. Keep the wrap-qt phase
since the non-GUI version is also a QT program.
