[PATCH 1/2] libmount: dont ignore autofs mounts by default

[Ian Kent <raven@themaw.net>]

Making libmount ingore autofs mounts by default can be a problem for
systemd, I remember now what the problem was.

autofs multi-mounts can be nested (and often are, think of a tree of
NFS exports) where there are autofs file system mounts within NFS
mounts and together with autofs mount triggers.

In this case systemd needs to see all the mounts at shutdown when it
is umounting the tree of mounts. We don't want to have to rely on
modifications having been made to systemd for this to work properly
so we can't make this the default behaviour in libmount.

Fixes: 22147e08c987 (libmount: use autofs mount hint to ignore autofs mount entries)
