Crud, I screwed up and gave you an intermediate version of the patch
which tried to do the same thing for rw_tree1.  For that to work, I'll
need to write a dtbs_equal_notordered test.

Corrected version below.

libfdt: Fix sw_tree1 testcase

There is a bug in the sw_tree1 testcase / utility which puts two
"compatible" properties in one node in the output tree.  This patch
fixes the bug, and also adds a new test checking that the sw_tree1
output is equal to test_tree1.dtb as its supposed to be, which should
catch future errors of this type.
