Make last(1) display the full log file.

I must have misread when I ported the original last(1) source code.
Instead of only processing the last 1024 entries, it reads them in in
chucks of 1024 entries at a time.

Unfortunately we cannot walk through the log file in reverse order,
which means we have to allocate a piece of memory to hold all the
entries. Call realloc() for each 128 entries we read.
