EDK II Contributions.txt: Note acceptable contribution licenses

We strongly prefer that contribtions be offered using the same license
as the project/module. But, we should document other acceptable
licenses for contributions.

This will allow package owners to more easily know if they can accept
a contribution under a different source license.

NOTE: This does not modify the wording of the "TianoCore Contribution
      Agreement 1.0" section

+5. It is preferred that contributions are submitted using the same

+   copyright license as the base project. When that is not possible,

+   then contributions using the following licenses can be accepted:

+   * BSD (2-clause): http://opensource.org/licenses/BSD-2-Clause

+   * BSD (3-clause): http://opensource.org/licenses/BSD-3-Clause

+   * MIT: http://opensource.org/licenses/MIT

+   * Python-2.0: http://opensource.org/licenses/Python-2.0

+   * Zlib: http://opensource.org/licenses/Zlib

+

+   Contributions of code put into the public domain can also be

+   accepted.

+

+   Contributions using other licenses might be accepted, but further

+   review will be required.
