So far, the tests for generating runtime overlays with dtc weren't checking the syntactic sugar. This adds such a test. Furthermore the existing tests were only minimally testing dtc's output for the overlay. This adds a test comparing the dtc output with the more or less manually constructed overlays we already have for testing libfdt's overlay application code. This does require some minor changes to that manually constructed overlay which don't change the sematics but re-order / rename things to match the way dtc does it.
