[TEST] Increase timeout in order to allow jobs to terminate

Over time, the number of tests performed for each board increased, which in turn resulted in some jobs failing to finish tests within the 4h timeout. In future, split test jobs will be planned according to the type of tests (probe, functional or stress) performed.
