Subject: [PATCH] binfmt: Don't install dependency links at install time for
 the binfmt services

use [Install] blocks so that they get created when the service is enabled
like a traditional service.

The [Install] blocks were rejected upstream as they don't have a way to
"enable" it on install without static symlinks which can't be disabled,
only masked. We however can do that in a postinst.

Upstream-Status: Denied
