Summary
Revert r367291 (KEYWORD: shutdown for rc.d/zfs)

The problem is that zfs is asked to stop too early in the shutdown
sequence. Other services, such as syslog may still be running and have some
files open (e.g., under /var/log). This of course causes the messages like:

  cannot unmount '/var/run': umount failed
  cannot unmount '/var/log': umount failed
  cannot unmount '/var': umount failed
  cannot unmount '/usr/home': umount failed
  cannot unmount '/usr': umount failed
  cannot unmount '/': umount failed

For now, let's remove the shutdown KEYWORD from the zfs service, as people are
reporting problems in their setups:

In the future, we may think of stopping zfs on shutdown after all the other
services and just before init(8) exits. Another interesting option might be to
a new rcorder(8) KEYWORD like "shutdownjail", but this idea would need to be
discussed a bit.
