catalyst: Drop unbind()
mount_namespaces(7) says
A mount ceases to be a member of a peer group when either the
mount is explicitly unmounted, or when the mount is implicitly
unmounted because a mount namespace is removed (because it has
no more member processes).
As a result, we can rely on exiting the mount namespace to unmount the
bind mounts.
