fix Issue 16349 - better curl retry for install.sh script

- curl's --retry option isn't really helpful b/c no timeouts are
  activated by default
- use a retry loop with increasing sleep times instead
- enable connection (5s) and download (<1KB/s for 30s) timeouts
  (using --max-time is too tricky b/c of the unknown download sizes)
