HaikuDepot crashes when system is offline

[grexe]

since Haiku does not automatically bring up my wireless network (known and already several times connected, separate issue/feature request), I often forget that I am still offline.

While SoftwareUpdater checks network access at startup and properly fails if offline, HaikuDepot does not, but crashes later. Let's fail fast and be consistent, so HaikuDepot should at least report that it is not connected to the net (user might still want to change config or inspect installed apps, so it should not force nor expect being online all the time).

crashlog, has time far in the future due to system being offline, so maybe that's causing the issue
