utmpdump: fix localtime() error handling

If current TZ has no representation of a given time_t then localtime()
would return NULL and break the next strftime().

In practice this happens very likely on systems with 64bit time_t when
parsing broken binary data. Seen on aarch64 (and probably s390) using
our (incompatible) test wtmp data.
