zoneadmd shouldn't rely on autofs
During zone filesystem unmounting, it is possible for zoneadmd to call into autofs_cleanup
which directly makes a syscall into the the kernel's autofs module. If a distro chooses not
to deliver autofs, then this will fail and short-circuit zoneadmd's filesystem cleanup. We could
improve zoneadmd to handling a missing autofs module more gracefully.

To test this, I ran it on our Racktop platform and triggered the error path during zone shutdown to reproduce the aborted cleanup. After the fix, I retested and the loop now reports the problematic unmount correctly. The zone also continues to shutdown normally when there is no problematic unmount to trigger the error path.
