acpid: use shutdown for poweroff, if available, not /sbin/poweroff

It's preferable to use "shutdown -hP now" to ensure that the runlevel is
known, preventing this message on the system console and log:

  WARNING: could not determine runlevel - doing soft poweroff
    (it's better to use shutdown instead of poweroff from the command line)
