Subject: [PATCH 3/3] Delay PkUpdates::checkUpdates calls if the network state
 is offline

If PkUpdates::checkUpdates is called and the network state is offline,
delay the check for updates until the network is online again.

This fixes the problem that when the user logs in, the applet is run
and just after the PkUpdates object is created, checkUpdates is called
(from main itself). But at that point the user might have not entered
the wifi password so the check would fail. Now, if we detect there's
no network, we just delay the check until the network state is online.
