dtc: Count testcases and results in the dtc/libfdt testsuite

There are quite a lot of testcases in the dtc testsuite (recently
imported from libfdt).  It can be easy to miss a stray FAIL result in
the midst of all the rest.  To improve this, this patch adds a summary
to the end of the testsuite results giving the total number of tests
along with the number of PASSes FAILs and other results.
