The script that monitors activity in the serial assumes that something
was wrong if it does not detect activity in 60 seconds, rebooting the
device and re-trying the test again.
While this timeout is enough for most cases, in some cases it is not
enough. For instance, when executing piglit testsuite it takes quite a
few time to generate the results after the test is done.
This allow to setup a custom timeout (`BM_POE_TIMEOUT`) in the proper
jobs.
