use **kwargs to pass along additional arguments to ones_like

This is a fix to be included in a release before merging #1669, as the changes there would break xarray with no possible work-around. Not sure if we need tests, as those would probably be tricky to write and maintain.

@hgrecco, @jules-ch, I'd like to have a bugfix release some time soon, and include #1669 in the next release. Would that be possible? (Also, I'd be happy to help make that happen)

• Executed pre-commit run --all-files with no errors
• The change is fully covered by automated unit tests
• Documented in docs/ as appropriate
• Added an entry to the CHANGES file
