Subject: [PATCH] unit: When stopping due to BindsTo=, log which unit caused it

I'm trying to track down a relatively recent change in systemd

which broke OSTree; see https://bugzilla.gnome.org/show_bug.cgi?id=743891

Systemd started to stop sysroot.mount, and this patch should help

me debug why at least.

While we're here, "break" on the first unit we find that will

deactivate, as there's no point in further iteration.

(cherry picked from commit 98f738b62047229af4a929d7996e2ab04253b02c)
