add information about origin db
that patch adds information about "installed repo"(origin db name) to local db of the package.
the information is gathered when installing package via pacman(or other package manager using libalpm) or updating system(which results into installing package, but with newer or older version).
the purpose of that patch is to actually know from which repository N package was installed and track issues with repositories easily instead of trust user about origin the package.

This should also help for reporting bugs at the packaging Gitlab tracker, that users need to provide this information(pacman -Qi <package> | grep 'Installed From'). so that it will be visible, if the package is installed from the official, custom/third party repo.
