Romain Naour e0166ecba0 support/misc/gitlab-ci.yml.in: retry a job only if it failed due to a runner issue
Each time a new pipeline is triggered, some jobs may fail due to
temporary issue with a Gitlab runner (network, power supply, docker or
maintainance).

Most of the problems are "runner system failure" [1] and require to
retart each failed jobs manually by maintainers to complete the
pipeline with only real failures if any.

The "retry" keyword allows to configure how many times a job is retried
if it fails. "retry:when" allows to retry a failed job only on
specific failure types like "runner_system_failure".

While at it, retry a job if it failed due to a timeout failure (this
timeout means that the job was pending for more than 24h) [2].

Such timeout failures occur on pipelines testing each Buildroot's
defconfig since there is not enough gitlab runner available to build
all of them within 24h.

Retry only jobs that are more likely to wait for a runner
(generate-gitlab-ci-yml, runtime_test_base, defconfig_base and test_pkg).

[2] https://gitlab.com/buildroot.org/buildroot/-/jobs/4936949530 (timeout failure or the job got stuck)
