[PR #11773/8fbb43e6 backport][stable-12] Ensure standard locale in run_command (group5-batch2) (#11806)

Ensure standard locale in run_command (group5-batch2) (#11773)

* ensure standard locale in run_command (group5-batch2)

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

Modules updated: cronvar, dnf_versionlock, dpkg_divert, flatpak_remote, hg.



* add changelog fragment for group5-batch2
