This will fix the test failure on the netbsd-arm builder, but it is not
quite a real fix.

struct statvfs changed between NetBSD 9 and NetBSD 10, with notably the
"spare" member switching from [4]uint32 to [4]uint64. In addition, there
is a new member at the end with label information, if available. The
netbsd-arm builder runs on NetBSD 10, so it runs into an issue
casting the binary data into a Statvfs_t with the wrong padding.

I don't know why the issue does not happen on arm64.

It does not happen on 386 and amd64 because these builders are running
NetBSD 9 still.

The real fix would be to use the statvfs90 compat syscall on NetBSD 10
and up, but not on 9 and below.

Fixes golang/go#76097.

sockaddrIUCVToAny used the wrong size to for copying to RawSockaddrAny.
We found this by running the test with ASAN.
