Auto merge of #2776 - cww0614:socks_txtime_mips_musl, r=Amanieu

Enable sock_txtime on mips musl target

The struct and related constants were originally added in #2415. But they weren't enabled for mips musl target because the kernel version of the build image was old and they couldn't pass the build. Now the kernel version of the build image is already updated and I think we could enable them for mips musl target
