Increase the sleep time to 5 sec in chameleon_test.reconnect_output()

between unplug and replug. This makes display autotests run more reliably,
in particular for nyan_big to restart from the disabled state.

BUG=chromium:408376
TEST=Run display_EdidStress on nyan_big and see that chameleond does not
complain about unstable input or output.
