login: update 32bit utmp correctly on 64bit system

On 64-bit platforms such as x86_64, glibc is usually built with 32-bit
compatibility for various structures. One of them is utmp.

What this means is that gettimeofday(&ut.ut_tv, NULL) on x86_64 will
end up overwriting the first parts of ut_addr_v6, leading to garbage
in the utmp file.
