Do not scan autofs mount points

Accessing mount points to determine free space actually triggers a
mounting operation of autofs mounts. This results in all autofs mount
points to be always-mounted while gkrellm is running, something which
is hardly desirable.

Thanks to Gerard Neil for submitting this patch.
