Előd Illés 632b30df6d Fix list_eol_stale_branches.sh to list only stale branches
clone_repo script does not fail if the branch does not exist, but
checks out the master branch [1], so we have to make sure the required
branch exists.

This patch also adds a check that there were no more patches merged
after the given branch was tagged EOL.
