dlt-daemon-connection: Start up even if not all bindings are valid (#380)

dlt-daemon allows configuration of multiple addresses.
Before this commit the daemon exits when the first binding fails.
This commit changes the behavior so that the daemon only exits
if none of the configured addresses can be opened.
