Add rtnetlink.h, if_link.h, if_addr.h to Android

[tiann]

Here is the NDK header:

rtnetlink.h
if_link.h
if_addr.h

It is the same with Linux header, so i copied it from:https://github.com/rust-lang/libc/blob/master/src/unix/linux_like/linux/mod.rs

It seems that x86_64 header of NDK is different with aarch64, i will figure it out

[tiann]

There are two problems:

1. if_addr.h header seems not included in x86 CI ? (I don't known how the CI generated the main.c, but i have checked the header, it is the same with aarch64...) All the IFA_* variable are not exist..
2. the CI used ndk is ndk-21d, the header if_link.h doesn't contain: IFLA_PROP_LIST, IFLA_ALT_IFNAME, IFLA_PERM_ADDRESS, IFLA_PROTO_DOWN_REASON

So i remove the if_addr.h temporarily, and i remove the four IFLA_* variable. There are two things to do:

1. upgrade the CI ndk toolchains.
2. fix if_addr.h

But i think the upgrade may occur other issues, after i fixed it, i will make another PRs

You could tweak the test here to include additional headers:

libc/libc-test/build.rs

Line 1472 in f292633

fn test_android(target: &str) {

Thank you, i have updated the header
