tests: Allow dtbs_equal_unordered to ignore mem reserves

Browse source 
For some upcoming tests we want to be able to test if two trees are
equal, but we don't care about the memory reservation map.  So, this
adds an option to the dtbs_equal_unordered test helper which tells it
to ignore the reserve map.
