[git commit] last: fix ignoring the first login entry

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=782e3fc2b4012958d43e964064fd2f2806d46106
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

The first login entry is ignored if a log file contains more than one
entry. To fix it, do not break the while loop if the offset is zero.
