Frederik Rietdijk 22aef72ff1 python: get rid of msgpack-python, fixes #48864 ...

We already have msgpack, which is the same. Building a Python env with
`spacy` resulted in a collision between an `.so` provided through both
`msgpack` and `msgpack-python`.

I don't know why `transitional = True` was set. These kind of things
should be documented!
