[yocto] iptables not building on master

[Robert Yang]

Hi Tom,

Thanks for the update, the root cause is that iptables offers
a kernel header file include/linux/types.h, but it mis-matches
the kernel in the sysroot, we can add this:

#define __aligned_u64 __u64 __attribute__((aligned(8)))

to:

iptables-1.4.12.2/include/linux/types.h

to fix this problem.

Another solution is that as Dexuan suggested we change the order of
the include header files, but I'm afraid that may cause other problems,
since I think that the pkg's own header file should have a higher priority
than the system's, so I think that the current order is correct.

I will send a pull request after enough testing.

// Robert
