tools/lib/subcmd/pager.c: do not alias select() params
commit ad343a98e74e85aa91d844310e797f96fee6983b upstream.
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);
