awx-task fails for git

Failed to set a new url https://github.com/ansible/ansible-tower-samples for origin:

fatal: detected dubious ownership in repository at '/var/lib/awx/projects/_6__demo_project'

To add an exception for this directory, call:

    git config --global --add safe.directory /var/lib/awx/projects/_6__demo_project\n

• Add Command git config --global --add safe.directory '*' to build process

• Audit the above to ensure it's the right path as git config --global --add safe.directory '/var/lib/awx/projects/*' may be better.
