KAFKA-17479 Fail the whole pipeline if junit step times out [4/n] (#17121)

Fixes an issue where the CI workflow could appear to be successful in the event of a timeout and no failing tests. Instead of using Github Action's timeout, this patch makes use of the linux `timeout` command. This lets us capture the exit code and handle timeouts separately from a failed execution.
