stream-clone: filter possible missing requirements using all supported one

The `supportedformat` requirements is missing some important requirements and it
seems better to filter out with all requirements we know, not just an
"arbitrary" subset.

This is especially relevant as we about to phase out the `supportedformat` class
attribute.

(a backport of this change to stable should be sent soon).
