passt-repair: Add directory watch

It might not be feasible for users to start passt-repair after passt
is started, on a migration target, but before the migration process
starts.

For instance, with libvirt, the guest domain (and, hence, passt) is
started on the target as part of the migration process. At least for
the moment being, there's no hook a libvirt user (including KubeVirt)
can use to start passt-repair before the migration starts.

Add a directory watch using inotify: if PATH is a directory, instead
of connecting to it, we'll watch for a .repair socket file to appear
in it, and then attempt to connect to that socket.
