[PR #11765/2297a5c8 backport][stable-12] Ensure standard locale in run_command (group4-batch1) (#11792)

Ensure standard locale in run_command (group4-batch1) (#11765)

* ensure standard locale in run_command (group4)

Adds ``LANGUAGE=C`` and ``LC_ALL=C`` to the ``environ_update`` passed to
``run_command()`` calls in modules that parse command output, to prevent
locale-dependent parsing failures on non-C-locale systems.

Modules updated: dconf, pkgng, terraform.



* add changelog fragment for group4



* add PR link to group4 changelog fragment



* fix changelog fragment: rename with PR prefix, fix URL order
