include: include <std{bool,int}.h> via <nft.h>

There is a minimum base that all our sources will end up needing. This
is what <nft.h> provides.

Add <stdbool.h> and <stdint.h> there. It's unlikely that we want to
implement anything, without having "bool" and "uint32_t" types
available.

Yes, this means the internal headers are not self-contained, with
respect to what <nft.h> provides. This is the exception to the rule, and
our internal headers should rely to have <nft.h> included for them.
They should not include <nft.h> themselves, because <nft.h> needs always
be included as first. So when an internal header would include <nft.h>
it would be unnecessary, because the header is *always* included
already.
