package/docker-compose: add patch to allow recent 2.x releases of python-requests

setup.py explicitly listed a maximum allowed version of python-requests,
causing runtime failures with the python-requests version we have:

FAIL

Upstream regularly updates setup.py as new python-requests releases are
made, but it is unknown why new python-requests releases (which are supposed
to be backwards compatible) should not be allowed right away.

Add a path submitted upstream to only disallow new major versions, similar
to how the other dependencies are handled.

+Subject: [PATCH] setup.py: allow all recent 2.x requests releases
+
+Instead of having to update this for each new requests release.
+
+It it not quite clear why the restriction was added in the first place in
+commit b0480b4d04e (Bump SDK version to latest), but change it to simply
+disallow the upcoming 3.0 release to match what is done for the other
+modules.
