Improve error message when job pod failed with wrong arch

People often mistakenly do use wrong arch in our pipelines or forget to put arm64 or amd64 in pipelines:

Using FF_USE_POD_ACTIVE_DEADLINE_SECONDS, the Pod activeDeadlineSeconds will be set to the job timeout: 2h0m0s...

ERROR: Job failed (system failure): prepare environment: waiting for pod running: timed out waiting for pod to start. Check https://docs.gitlab.com/runner/shells/#shell-profile-loading for more information

Can you please improve the error message to be more accurate?

It is not a timeout. To be more accurate:

Job failed (system failure): could not start job because of wrong architecture in container image

Maybe also show more messages from EventList.
