Fix select decoding with bogus (huge or negative) nfds.
We used to allocate and fetch bit arrays using a sanitized
length, but then iterate over them with "j < arg[0]" condition,
where arg[0] is not sanitized. This segfaults if arg[0] is huge
or negative. This change fixes this.
Add test/select.c to capture the case.
