python: Change python 2.7.9 to use libffi from the system

Changes in python 2.7.9 from 2.7.3 cause issues when building the in
tree libffi for ctypes. These issues primarily affect less common
platforms (e.g. MicroBlaze) that are supported by libffi but the python
overrides for the in tree libffi are not able to detect correctly.

This patch changes the python 2.7.9 recipe to match how the python 3
recipe handles libffi by configuring the build to use the system
libffi. This brings consistency between the libffi used for different
python versions as well as with the system.
