ci: Prepare for cross-building binaries

Include the system name in the cross-built binary file, and put it under
`iocaine-binaries/latest`, rather than `iocaine/${{ version }}`, to
match how the container image is tagged. Releases will have their own
version.

Documentation updated to point to the new place.
