Create Symlink /usr/bin/ansible-playbook-3 when not exist

ansible-playbook-3 binary is no longer shipped with
ansible 2.9 package[1], so let's create it if it doesn't
exist. Once all usages of ansible-playbook-3 are removed
these all compatibility tasks can be cleaned up.

Also remove symlink creation of /usr/local/bin/ansible-playbook*,
as those were created temporary for fedora support[2].
