Subject: [PATCH] tools/lib/subcmd/pager.c: do not alias select() params

Use a separate fd set for select()-s exception fds param to fix the

following gcc warning:

pager.c:36:12: error: passing argument 2 to restrict-qualified

               parameter aliases with argument 4 [-Werror=restrict]

  select(1, &in, NULL, &in, NULL);

            ^~~        ~~~
