This restores show_pid_array() output in legacy locales on the console. Only one call to get_process_cmdline() is changed, all others retain utf8-only mode. This affects systemd-cgls, systemctl status, etc, when working locally. Calls to get_process_cmdline() that cross a process boundary always use utf8. It's the callers responsibility to convert this to some encoding that they use. This means that we always pass utf8 over the bus.
