sbus_tests: Add some testing of dispatch and handler code
This starts a DBus server with some handlers, and runs some method
calls against it.
Note that we don't use the codegen in the sbus_tests, as we sorta
want to test this non-codegen related functionality on its own before
we run the sbus_codegen_tests.
