Make the get_sources shell script support flat layout
The idea of this commit is to make get_sources.sh support both the 'traditional' git layout used on dist-git for CentOS Linux where the spec files are stored in a SPECS folder and the patches in a SOURCES folder with the sha of the tarball being in a '.<pkg_name>.metadata' file as well as the 'flat' git layout that have adopted Fedora as well as CentOS-Stream (9+) where the spec files and patches are all stored at the top level directory of the repository and the sha of the tarball is present in a 'sources' file. This commit re-uses code from the fedpkg-minimal project which is license under the GPL (so the License field of the spec file for centpkg-minimal may need to be adjusted to MIT and GPL).
