FWIW, for a very similar problem (udev rules instead of polkit rules) bluez-qt 
has the CMAKE flag INSTALL_UDEV_RULE to disable installation of udev rules.

If have this in my .kdesrc-buildrc:
=====
options bluez-qt
    cmake-options -DINSTALL_UDEV_RULE=0
end options
=====

So, maybe add a KDE_INSTALL_POLKIT_RULE[S] (or ..._ACTION[S]) flag to allow 
disabling the installation of polkit stuff.
