shared/install: fix DefaultInstance expansion in %i
We should substitute DefaultInstance if the instance is not specified. Test case: [Install] DefaultInstance=bond1 WantedBy= foobar-i-%i.device $ systemctl --root=/ enable testing4@.service Created symlink /etc/systemd/system/foobar-i-bond1.device.wants/testing4@bond1.service → /etc/systemd/system/testing4@.service. (before, the symlink would be created as /etc/systemd/system/foobar-i-.device.wants/testing4@bond1.service) Fixes #4411.
