Remove unintended master-orientated ansible-role-requirements

This patch removes roles meant for a the master branch only from the
ansible-role-requirements file.

It also adds two search paths for roles in tests/ansible.cfg to ensure that
the bootstrap execution has access to both the pip_install and sshd roles.
