[PR #11778/42a1998b backport][stable-12] Ensure standard locale in run_command (group5-batch7) (#11805)

Ensure standard locale in run_command (group5-batch7) (#11778)

* Fix locale env vars in run_command() calls for group5 batch7 modules

Set LANGUAGE=C and LC_ALL=C via run_command_environ_update to ensure
locale-independent output parsing in zfs, zfs_delegate_admin,
zfs_facts, and zpool_facts.



* Add changelog fragment for PR #11778
