Regression tests **scan-build** and **exploded-graph-rewriter** was taged as not supporting Windows platform. The actual reason was that nobody checked that fact before running test on Windows. But the tests looks like they can work well reliing on the way they are written.
Removed tag UNSUPPORTED from scan-build tests.
Removed tag UNSUPPORTED from exploded-graph-rewriter tests.
Fixed path to exploded-graph-rewriter.py in local.cfg
Minor fix for exploded-graph-rewriter.py. It did not correctly convert dot to html.
Now all these tests locally pass on Windows. Shall be checked on other platforms.
