gitlab-ci: Display Avocado log content when tests timeout

Since commit ba2232bae6d ("gitlab-ci: Refactor code that show logs
of failed acceptances") we display the log content of failing tests
(Avocado "FAIL" event).

Since we are also interested in tests timeouting, update our global
Avocado config to display log content for the "INTERRUPT" event,
"possible when the timeout is reached" (See [*]).
