reno: Update master for xena Unmaintained status

The stable/xena branch has been deleted, so reno can't find its
release notes.  Use the xena-eom tag to indicate the end of the
Cinder project's maintenance of the Xena series.

This strategy is what we used for the yoga transition, and was
discussed at a cinder weekly meeting:
