last: fix utmplist usage

last(1) uses a global list of entries, this is unnecessary and it's
also mistake because the pointer to the list is not set to NULL when
last(1) opens another utmp file. For example:

 last -f /var/log/wtmp -f /var/log/wtmp-20150220

ends with unexpected free() call or sometimes with never ending loop.
