games-strategy/xbattleai: Port to C99, update EAPI 7 -> 8

Autoreconf fixes configuration failure due to C99 error, includes
are added unconditionally, because we now live in sane, homogenous
world, those are system files that ought to be on by default on any
linux system with libc and I don't want to touch autoconfig files
any more than what I need to.
