i2c-tools: change upstream and add python subpkg
~~Things I am still unsure about:~~
- ~~The subpackage name and short_desc~~
- ~~How to ensure the subpackage's version is the version of the python module (it is versioned separately)~~

Closes #36156

#### Testing the changes
- I tested the changes in this PR: **briefly**
    - [x] Distfile location change had no impact (same exact file as debian's)
    - [x] Package builds fine and with the right files in the right place
    - [x] Crossbuilds fine
    - [ ] Tested the python bindings
