[CI][C++][Go] Don't run jobs needs arm64 self-hosted runner on fork

[kou]

Describe the enhancement requested

We have some jobs that uses an arm64 self-hosted runner in cpp.yml and go.yml. But arm64 self-hosted runners are available only on apache/arrow. These jobs are failed by timeout on forks.

Example: https://github.com/kou/arrow/actions/runs/4626263855/jobs/8182817753

If these jobs are failed, notifications from GitHub are generated. They are noisy.

Component(s)
