Raise smart mirror Git backend timeout (#439)
CI fanout can ask the smart HTTP mirror to generate many large Git packs at
once. The default httpd CGI timeout is 60 seconds, which can kill a
queued git-upload-pack before it writes response bytes and surface to
Jenkins as an HTTP 502 checkout failure.
This gives git-http-backend a longer timeout budget in the smart mirror
container. The troubleshooting notes also call out the 60-second 502
signature so operators know to rebuild and restart the image during
rollout.
