narrow: move the wireprotocol narrow capability name to core

We are trying to integrate the whole of narrow logic into core and it will be
helpful for upcoming patches to have these capability names in core. The next
patch will move the ellipses capability to core also.

The exact motivation is to know whether we are cloning a ellipses repo or not
and adding an ellipses repo requirement.
