A couple of minor fixes

1. Fixing ExceptionHandlerTest.FirstChanceHandlerRuns:
   exit() is not an async-signal-safe function (http://man7.org/linux/man-pages/man7/signal-safety.7.html)

2. Fixing entry point signature in minidump_dump
  Changed "const char* argv[]" to "char* argv[]" to match the standard entry point signature

3. Updating .gitignore to exclude unit test artifacts
