Increase timeout for initial XDP portal session to 2s
release-2.x.y

Increase timeout for initial XDP portal session to 2s

It should still fail immediately when the portal isn't available, but
in my test VM with systemd automatically activating the portal when it's
first accessed, it can take 800ms or so. Wait for it instead of falling
back after 200ms.
