Update license clause to reflect actual licensing

Update spec file license to reflect current state

Several parts of libnvidia-container (and dependencies) are not BSD-licensed,
or are ambiguously-licensed. This updates the spec file to reflect current
state, including some comments so the reasoning isn't lost. If #74 is
resolved, this may change. I thought this might be useful in the interim either to make the spec file accurate or to assist in cleaning up. :)
