Ensure standard locale in run_command (group5-batch1) (#11768)

* ensure standard locale in run_command (group5-batch1)

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: apache2_module, composer, facter_facts, known_hosts module
utils, lvg_rename, macports, modprobe, monit, open_iscsi, pacman_key,
rhsm_release, rpm_ostree_pkg, sysupgrade.

* Remove lvg_rename from locale fix — superseded by PR #11746

PR #11746 (feat: use CmdRunner for LVM commands) takes priority and
will handle lvg_rename.py via CmdRunner refactor. Removing our
run_command_environ_update change to avoid conflict.
