Task #2669: Fixed problem reported by Alexander van Amesfoort.

CMake's 3.x create_symlink always overwrites existing files. This caused a circular link to mpirun.sh in ${CMAKE_BINARY_DIR}/bin, because that script is generated in that directory, but was clobbered immediately afterwards, due to the fact that lofar_add_bin_scripts() creates a symlink to that script in ${CMAKE_BINARY_DIR}/bin for testing purposes.
