Reordering of sample and tutorial bindings

The main idea here is to install the sample and
tutorial bindings in specific directory.

This will at the end help to package parts
of the binder.

It also includes a simplification of CMakeLists
files.

Also fix an error in packaging rpm.

Bug-AGL: SPEC-2165
