[PyROOT] Don't install the python modules twice

The binary python modules were moved one directory level down into the
ROOT and cppyy directories, so that they reside alongside the python
files in the same directories. The install rule for the python files
must therefore be extended to exclude the binary modules (PATTERN *.so
EXCLUDE) so that these are not installed a second time overwriting the
files installed by the install rule for the binary modules with another
copy with the wrong file permissions.

Also use the no-version option for the cppyy binary module as is
already done for the pythonization binary module, since it is now
installed in the python directory. Before it was installed in the
library directory with an unversioned symlink in the python directory.

(cherry picked from commit 5b09965)
