Subject: [PATCH] Fix build with Python 3.8 and --no-undefined linker flags

Currently the build uses the CMAKE_SHARED_LINKER_FLAGS for both
the libArcus shared library as well as the Python module. Starting with
Python 3.8 the Python module is no longer linked to libpython, and thus
some symbols stay undefined.

The correct build type for python modules is "MODULE", which uses the
distinct CMAKE_MODULE_LINKER_FLAGS. This allows to keep the
'-Wl,--no-undefined' linker flag for libArcus.
