app-eselect/eselect-python: Use C wrapper for python{,2,3}, #568974
Use python-exec2-c to wrap /usr/bin/python{,2,3}, rather than the Python wrapper. This is both more correct, and fixes Prefix support since non-Linux systems require programs referenced in shebangs to be real executables rather than scripts.
