ipsec.widget.php: Tunnel Status incorrect
IPsec tunnel status is shown correctly on Status > IPsec, but the IPsec widget on the dashboard does not show the correct status. A tunnel that is "up" is counted in the inactive column on the Overview tab and the same tunnel is shown as down on the Tunnel tab. The tunnel is definitely up and passing traffic.
Change IPsec widget tunnel status to handle newer strongSwan childid format. Fixes #7499
