Make sure IOV_MAX is defined.

We stopped defining IOV_MAX on non-Windows systems in 75357ab94, on
the assumption that every non-Windows system defines it in <limits.h>
as required by X/Open.  GNU Hurd, however, doesn't follow that
standard either.  Put back the old logic to assume 16 if it's
not defined.
