Subject: [PATCH] makepkg: make 'not a clone of' visible with a new error code

Add a new error code to expose the 'not a clone of' error state of some source
providers (git and fossil). This allows other tools integrating further and
handle this specific error state.

One usecase evolves around frequently changing source locations in PKGBUILDs
of packages in the AUR.
