ci/vc4: allow custom timeout values for activity

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.
