python-native: add nativepython symlink

Add a symlink to the native Python so that scripts can just invoke
"nativepython" and get the right one without needing absolute paths (these often
end up too long for the #! parser in the kernel as the buffer is 128 bytes
long).

The name "nativepython" was chosen to match the existing "nativeperl" which
serves the same purpose.
