Auto merge of #2830 - tiann:master, r=JohnTitor

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

Here is the NDK header:

[rtnetlink.h](https://android.googlesource.com/platform/prebuilts/ndk/+/dev/platform/sysroot/usr/include/linux/rtnetlink.h)
[if_link.h](https://android.googlesource.com/platform/prebuilts/ndk/+/dev/platform/sysroot/usr/include/linux/if_link.h)
[if_addr.h](https://android.googlesource.com/platform/prebuilts/ndk/+/dev/platform/sysroot/usr/include/linux/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
