CMake: Work around building dbus 'controller' example with qmake

Browse Source 
Similar to what has been done in 5138a970f3, we need to adjust the
remotecontrolledcar/controller dbus example to be built with qmake.

In the CI we first build the examples with CMake in the source
directory. That creates some generated source files in the dbus example
dir.

Then, the examples are (will be) built ouf of source with qmake, and
those generated source files will be placed in the build directory.

When building with MSVC, there's a peculiarity with nmake/jom's
inference rules that lead to picking up the generated car_interface.cpp
from the source directory, instead of the build directory.
See QTBUG-13496 for details.

car_interface.cpp, built with CMake is generated to include
car_interface.moc.
car_interface.cpp, built with qmake does not have this include, but the
build system calls moc on car_interface.h.

All this leads to duplication of the meta object for
OrgExampleExamplesCarInterfaceInterface, preventing successful linking.

Work around this issue by turning off the generation of nmake/jom
inference rules.
