qemu-io: Clean up global variable shadowing

Fix:

  qemu-io.c:478:36: error: declaration shadows a variable in the global scope [-Werror,-Wshadow]
  static void add_user_command(char *optarg)
                                     ^
  /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/getopt.h:77:14: note: previous declaration is here
  extern char *optarg;                    /* getopt(3) external variables */
               ^
