Patch to make pre19 work with NetBSD

[David Rankin]

The pre19 code assumes that struct lastlog either exists in lastlog.h or
isn't there. On NetBSD, struct lastlog is defined in utmp.h. Even worse,
the non-lastlog code in login.h is terrible on NetBSD (since NetBSD
doesn't have a ut_type struct member).

With the patch below, openssh will compile and run on NetBSD again.

Thanks,
David
