[PR #11779/d6909578 backport][stable-12] Ensure standard locale in run_command (group5-batch8) (#11804)

Ensure standard locale in run_command (group5-batch8) (#11779)

* Fix locale env vars in run_command() calls for group5 batch8 modules

Set LANGUAGE=C and LC_ALL=C via run_command_environ_update to ensure
locale-independent output parsing in lxc_container, ip_netns,
and capabilities.



* Add changelog fragment for PR #11779
