To add some context to this patch, the issue is with the main package program
crashing with current Python 3.10 on execution (building doesn't fail):

```
$ guix shell -CW which procps python-py3status
user@computer /tmp [env]$ guix describe
  guix 14c0380
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 14c03807ba4bc81d42cf869f5b827f7da54ff843
user@computer /tmp [env]$ py3status

Newer versions use `from collections.abc`.
