hurd: Add missing struct __timeval for 64bit support

[sthibaul]

This is the same as linux_like/linux/gnu's __timeval for ut_tv for 64bit architectures.

Can you post a link to the relevant docs/source here? libc-test/semver should probably also get a new hurd file with this struct (more can be added later) if you are able to run the test.

As mentioned, this is exactly the same as linux with glibc: https://github.com/rust-lang/libc/blob/main/src/unix/linux_like/linux/gnu/mod.rs#L75

for the same reason: the ut_tv field of struct utmpx uses it in the 64bit case: https://github.com/rust-lang/libc/blob/main/src/unix/linux_like/linux/gnu/mod.rs#L584 and https://github.com/rust-lang/libc/blob/main/src/unix/hurd/mod.rs#L1058

because glibc uses a 32-bit-compatible timeval for that field: https://sourceware.org/git/?p=glibc.git;a=blob;f=bits/utmp.h;h=27cb536800c46d67c0627dddb66db4ad737d356f;hb=HEAD#l72

libc-test/semver should probably also get a new hurd file with this struct

We don't have a hurd file there for now.

Thanks for the follow up, sounds reasonable to me.
