[PR #11775/7c52f1c4 backport][stable-12] Ensure standard locale in run_command (group5-batch4) (#11808)

Ensure standard locale in run_command (group5-batch4) (#11775)

* Fix locale env vars in run_command() calls for group5 batch4 modules

Set LANGUAGE=C and LC_ALL=C via run_command_environ_update to ensure
locale-independent output parsing in logstash_plugin, lvg, mas,
osx_defaults, and pkgutil.



* Add changelog fragment for PR #11775
