autofs-5.1.5 - use ignore option for offset mounts as well

From: Ian Kent <raven@themaw.net>

The pseudo option "ignore" (that's used as a hint that applications
should ignore this mount when reporting a list of mounts) has been
added to direct and indirect mounts but hasn't been added to offset
mounts.
