Fix StringExtractor.h issues.

Summary

Fix StringExtractor.h issues.

• source/Plugins/Process/MacOSX-Kernel/ProcessKDP.cpp (#include "Utility/StringExtractor.h): Not needed, this is already included by ProcessKDP.h

• unittests/Utility/StringExtractorTest.cpp (#include "Utility/StringExtractor.h): Update include path to the new location.

This doesn't address the issue with debugserver which may be a more controversial fix.

I'm not absolutely sure if moving the StringExtractor was the right choice on my part, but this does definitely does not make it worse.

Seems like StringExtractor.h wasn't actually needed in ProcessKDP.h so it should have been removed from there instead of from the .cpp file.
