mc: update to 4.8.29, cleanup, adopt.
https://github.com/void-linux/void-packages/pull/38079

Description:
Takes care of python2 scripts, and documents what packages are needed for each "extfs" backend script.

#### Testing the changes
- I tested the changes in this PR: **YES**
    It is impossible to test the s3 backend without an AWS S3 account, but the patch is used in other distros.
