9eca3c58c5 Add script to launch fuzzing continuosly (Riccardo Casatta)

Pull request description:

  Continuosly cycle over fuzz targets running each for 1 hour.

  I use this script on a server of mine and maybe sharing the script incentives other doing the same

    ACK 9eca3c58c5. I do have the resources to actually run it, but I successfully ran it locally with 5 sec cycle for testing.
