Refactor openshift_facts BIOS vendor discovery

In Ansible 2.4, `get_file_content` is moving
 from ansible.module_utils.facts
 to   ansible.module_utils.facts.utils

However, the method is no longer needed as the BIOS vendor fact can be
retrieved
from a standard Ansible fact, `ansible_system_vendor`.

i.e.:
        "ansible_system_vendor": "Google",
