chromite: Increase connection timeout after reboot.

When rebooting a device, chromite waits 120 seconds before declaring a
reboot failure.  In developer mode, some devices can exceed this limit
by a few seconds.  Up the limit such that cros flash works more
reliably.

BUG=None
TEST=Manually tested.
