fix(ci): pass SSH keep-alive via rsh param and drop redundant compression

The `options` parameter does not exist in burnett01/rsync-deployments,
so SSH keep-alive settings were silently ignored, causing broken pipe
errors on large transfers. Move them to the correct `rsh` parameter,
remove `-z` (images are already compressed), and add `--timeout=300`.
