(GH-25) Reset files after build process

- As part of the build process, the configuration files for DupFinder
and InspectCode are modified, which leaves two pending changes in git.
These changes shouldn't be checked in.  Once the build has finished,
re-checkout these files, to revert them back to their previous state
