If getopt_long() is called for a list of arguments and it is freed, then calling getopt_long() for another list will trigger use-after-free. The function proc_cmdline_filter_pid1_args() may be called before or during parsing program arguments (typically named as parse_argv()), hence we cannot use getopt_long() in proc_cmdline_filter_pid1_args(). Fixes #28366.
