Make sure any python search finds Python3.

FindCWrap issues another find_package(PythonInterpret).
By setting the PYTHON_EXECUTABLE variable we make sure it
will find python3

This also fixes the CMake confusions about multiple linker paths

```
Make Warning at cmake/Modules/OpmSatellites.cmake:320 (add_executable):
  Cannot generate a safe linker search path for target test_ERft because
  files in some directories may conflict with libraries in implicit
  directories:

    link library [libpython3.7m.so] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
      /usr/lib/python3.7/config-3.7m-x86_64-linux-gnu

  Some of these libraries may not be found correctly.
```
