scanf.3: Clarify that %n supports type modifiers
My initial reading of this was that type modifiers were probably
not supported. But they are, and this is actually documented
further up, in the type modifiers documentation. But to make it
clearer, let's copy the language that printf(3) has in its %n
section.

Various pages: Remove unused <sys/types.h>
The manual pages are already inconsistent in which headers need
to be included. Right now, not all of the types used by a
function have their required header included in the SYNOPSIS.
If we were to add the headers required by all of the types used by
functions, the SYNOPSIS would grow too much. Not only it would
grow too much, but the information there would be less precise.
Having system_data_types(7) document each type with all the
information about required includes is much more precise, and the
info is centralized so that it's much easier to maintain.
So let's document only the include required for the function
prototype, and also the ones required for the macros needed to
call the function.
<sys/types.h> only defines types, not functions or constants, so
it doesn't belong to man[23] (function) pages at all.
I ignore if some old systems had headers that required you to
include <sys/types.h> *before* them (incomplete headers), but if
so, those implementations would be broken, and those headers
should probably provide some kind of warning. I hope this is not
the case.
[mtk: Already in 2001, POSIX.1 removed the requirement to
include <sys/types.h> for many APIs, so this patch seems
well past due.]
