Orig tarball should be included alongside the modified source tarball

[herpiko]

There are two kind of packages:

Native package

The source code and debian spec are in one directory tree. Example: base-files, apt, etc. The end result of pipeline should be:

• *.dsc - dsc
• *.deb - Debian pacakge
• *.tar.* - source code

Third party package

The package that does not have debian spec in their source tree. Example: gnome, firefox, etc. We'll define the debian spec ourself. The end result are:

• *.dsc - dsc
• *.deb
• *.tar.* - the source code after patches get applied
• *.orig.tar.* - original source code before we apply any patches.

*.orig.tar.* only need to be updated if we update the software to higher version. The *.orig.tar.* should respects the source code of the new version.

Any kind of patch should be happen in debian spec directory.
