debian: Fix systemd service names in dependency specifiers

Commit 9016f9d9 ("change service file installation") changed service files to use instance names for specifying the interface. However, the files were not changed to use the new names.

This bug has been reported in Ubuntu [1] and OpenEmbedded [2], where a patch has been proposed. But timemaster.service was not fixed there. This patch fixes them both.
