Making polkit-qt-1 a tier1 framework

[David Faure]

Talking about polkit-qt-1, your last commit there broke compilation in CI:

https://build.kde.org/job/polkit-qt-1%20master%20kf5-qt5/PLATFORM=Linux,compiler=gcc/5/console

kf5-qt5/core/polkitqt1-subject.cpp:186:111: error: ‘polkit_system_bus_name_get_user_sync’ was not declared in this scope

Same in the other CI, http://ci-logs.kde.flaska.net/45/4528ea9f808f7f9de56dee70626040bed2b4b67c/rebuilddep/rebuilddep-kf5-qt55-clang-el7/5477297/shell_output.log

Thanks for taking a look.
