include: include <stdlib.h> in <nft.h>

It provides malloc()/free(), which is so basic that we need it
everywhere. Include via <nft.h>.

The ultimate purpose is to define more things in <nft.h>. While it has
not corresponding C sources, <nft.h> can contain macros and static
inline functions, and is a good place for things that we shall have
everywhere. Since <stdlib.h> provides malloc()/free() and size_t, that
is a very basic dependency, that will be needed for that.
