python: rework python symlinks installation
This change adds a patch to python disabling the installation of the
python and python-config symlinks.
This allows Buildroot to control these symlinks' installation:
* the python symlink should be unconditionally installed in the target
tree, and the python-config symlink in the staging tree, since it is
only built and installed in the target tree if the user selected it;
* the python and python-config symlinks should only be installed in
the host tree when python(2) is the selection of the user for the
target.
Otherwise, when python3 is selected for the target, the host-python
may be required to built some packages. In such cases, the python
symlink should points to python3 (so should the python-config
symlink) to reflect the staging/target tree.
[Thomas: fix comments according to Yann's suggestions, and replaced
python(2) by python2, as suggested by Yann.]
