python: bump to 2.7.9

In addition to doing the bump, this commit also:

 - Refreshes all the patches
 - Removes python-003-properly-detect-if-python-build.patch, which has
   been applied upstream.
 - Passes the --without-ensurepip option, like is done in Python 3, to
   avoid having Python use PIP to automatically download stuff when it
   is being built.
 - PYTHON_LIBTOOL_PATH = NO is added to prevent Buildroot from trying
   to patch a version of libtool for which we don't have matching
   patches, which isn't a problem since we're anyway not using the
   part of the Python sources that uses libtool (it's the built-in
   copy of libffi, and we use the external libffi).
