lang/python31: Backport upstream kevent fix and use libffi from ports

Backport a change fixing use of kevent flags that was merged to Python
default, 3.3 and 2.7 branches, but not 3.2 and 3.1 that were in
security-only mode at the time of commit. [1]

- Add patch: patch-Modules__selectmodule.c

Based on patch by: David Naylor <naylor.b.david@gmail.com>

Unconditionally use libffi from ports because the Python 3.1 branch was
closed for maintenance when the import of libffi 3.0.13 took place. This
fixes _ctypes module build failure on i386. [2]

- Add global CONFIGURE_ARGS and LIB_DEPENDS
