cmd/link: refactor setCgoAttr

Browse Source 
setCgoAttr takes a lookup function, but there's only a single call and
setCgoAttr already has access to the lookup function passed at that
call. Simplify setCgoAttr by eliminating the lookup parameter and
calling the lookup function directly.

For #40724.
