firewire: core: add KUnit test skeleton for node tree

Some issues have been reported in node tree management. Refactoring
the topology-related code in the core is required. Adding unit tests
would help ensure that the refactoring does not introduce regressions.

This commit adds a KUnit test skeleton for this purpose.
