eyre: give scry function to generators

Browse Source 
In Ford Fusion, Clay builds generators but Dojo and Eyre run them.  Dojo
is already virtualized with a scry function, so +mule is fine, but Eyre
is not, so Eyre needs to use +mock and explicitly supply the scry
function.  This does that.  Fortunately, the produced result is simple
and easily clammable.

Fixes #3089
