Remove obsolete redhat-eventlet.patch

See I62ce43a330d7ae94eda4c7498782a655e63747fa for the gorey details on
why this exists.

As of this fix:

eventlet/eventlet#34

which was released in eventlet 0.13, we no longer need the patch.

This has now been removed from oslo-incubator, so this is really just
syncing that removal.
