Ensure standard locale in run_command (group5-batch10) (#11781)

* Fix locale env vars in run_command() calls for group5 batch10 modules

Set LANGUAGE=C and LC_ALL=C via run_command_environ_update to ensure
locale-independent output parsing in imgadm, smartos_image_info,
syspatch, portage, portinstall, xbps, and lbu.
