rpm: pass %{python3_version} to cmake

to force cmake to use the python3 and python3 modules for building
python3 bindings

on the debian side, it's okay to continue using "-DWITH_PYTHON3=ON", as

- cmake does normalize "ON" to 3
- debian's cmake extension lives on /usr/lib/python3/dist-packages/
  not in a specific /usr/lib/python3.x/dist-packages directory
