haxstring: Add parenthesis to macro arguments

WRITES(fd, *s) where s is a pointer to a struct string will
not compile, as the macro expands to write(fd, *s.data, *s.len),
which it expects s to be a struct string and attempts to use
s.data and s.len as pointers. This is, of course, erroneous.
The correct expansion is write(fd, (*s).data, (*s).len); while
write(fd, s->data, s->len) is desirable, it is not achievable with
a simple macro expansion. In any case, the parenthesis shall be
added.
