faf70c1f330a92612cf381d32c791e9ba445d3f2 Bump python minimum version to 3.9 (MarcoFalke)
fa8996b930886da712c09ffe4b58016b36c2ae5b ci: Bump i686_multiprocess.sh to latest Ubuntu LTS (MarcoFalke)
Pull request description:
All supported operating systems ship with python 3.9 (or later), so bumping the minimum should not cause any issues. A bump will allow new code to use new python 3.9 features.
For reference:
* https://packages.debian.org/bullseye/python3
* https://packages.ubuntu.com/focal/python3.9
* FreeBSD 12/13 also ships with 3.9
* CentOS-like 8/9 also ships with 3.9 (and 3.11)
* OpenSuse Leap also ships with 3.9 (and 3.11) https://software.opensuse.org/package/python311-base
This is for Bitcoin Core 27.0 in 2024 (next year), not the soon upcoming 26.0 next month.

Pull request description:
The minimum supported version of Python is 3.4 according to [dependencies.md](https://github.com/bitcoin/bitcoin/blob/master/doc/dependencies.md). This PR makes the Travis linter use this version in order to catch accidental use of modern syntax.
