Handle: add ConntrackDeleteFilter alias for backward compat

Commit c96b03b changed the signature
of this method to accept a list of filters and renamed it to
ConntrackDeleteFilters (plural).

This patch

- adds back ConntrackDeleteFilter as an alias
- marks it as deprecated in favor of the new version.
- adds missing stubs for other platforms
