[git commit] acpid: fix logging

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=1eafd4494706c21a87dc66e4e0afa8799b576cb5
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

Without this patch acpid can't log the events at all. Moreover it tries
to truncate log file every time.
