I'm experimenting with the new syscalls and noticed fio's support was
incomplete. This patch fixes some of those issues.

Additionally, until libc catches up, I've hacked in:
#include <unistd.h>
#include <sys/syscall.h>
#define preadv2(...) syscall(SYS_preadv2, __VA_ARGS__)
#define pwritev2(...) syscall(SYS_pwritev2, __VA_ARGS__)
