Merge 2bae3b04e0 into 0e09014df5

In the "Engines" tab on searx.space [1] nearly all engines report a

    TimeoutException: yep engine

As documented in issue #2444 [2], this problem can be fixed by increasing the
timeout. Note: on a local instance (`make run`) the timeout of 3sec was
sufficient / at least in my local test, but the balance of searx.space leads me
to believe that this tight timeout is usually not sufficient.
