File PyYAML-big-endian.patch of Package python3-PyYAML

pyyaml FTBFS on the s390x buildd.  It seems this is due to using int
where the libyaml API uses size_t.  I tested the attached patch in
zelenka.d.o's sid chroot, and at least the python2 build/test worked (it
failed with the same error as the buildd pre-patching).
