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.

At the moment we have some rudimentary tests of the fdt_overlay_apply()
function which don't rely on overlay generation support in dtc. This is
done by avoiding any external references in the sample overlay, in
particularly using the 'target-path' syntax instead of 'target' to avoid
needing external references in the fragment targets. Thus this test case
doesn't exercise libfdt's processing of the __fixups__ node at all.
We do test that somewhat in combination with dtc's overlay support.
However, in the interests of being able to quickly determine which side a
bug is on, it would be nice to exercise this without requiring the dtc
support.
This adds testcases to do so, by making some examples with manually
constructed __symbols__ and __fixups__ nodes. In addition we rename some
of the test data files and add some extra check_path tests to make it a bit
clearer what's going on here.
