r243914 broke the build for Linux

Hi Adrian,

r243914 broke the build for Linux:
http://lab.llvm.org:8011/builders/lldb-x86_64-ubuntu-14.04-cmake/builds/4798/steps/ninja%20build%20local/logs/stdio

Thanks,
Siva Chandra

This can be fixed by changing CMakeLists.txt of source/Plugins/Process to not call add_subdirectory() on win-minidump unless platform is Windows. Adrian is on vacation, but I can fix this tomorrow morning. If you need it fixed sooner, the change I mention should take care of it.

I had needed this fix as well, so I went ahead and pushed it.
