lang/python[xx]: backport upstream fix for CVE-2016-5636

Add patch for integer overflow in zipimport module to all our python ports.

While I'm here, get rid of -f flag in ${RM} invocation, because ${RM} already
expands to rm -f, so in result we are getting something like:

/bin/rm -f -f /wrkdirs/usr/ports/lang/python35/work/stage/usr/local/lib/libpython3.so
