Some utmp feature fixes for WATCH



[Part 2 of 2 from my just-found forgotten bug list :)]

With the WATCH feature, and without this patch, I used to get messages
like:

root has logged off 2 from .
 has logged on 2 from .
 has logged off p1 from somehost.
someuser has logged on p1 from somehost.

This clearly depends on the utmp-managing programs, but
I think it's correct to ignore the entries which do not
contain a name.
