wayland-ivi-extension: Build unit test apps

The wayland-ivi-extension package provides unit test applications.
The recipe was modified to build those apps and install them on the target
in a separate ipk/rpm package.
The test apps are not compatible with ptest. Ctest is required to run them
on the target.
