package/python-paho-mqtt: fix merge from next

In master, we backported a patch from upstream, to fix running on python
3.10. But at the same time, on next, we bumped the version, where that
change was present.

Now, next has been merged back into master, and the patch obviously does
not apply anymore.

Remove the patch, it is no longer needed.
