Passing copy==1 to syslook is only necessary to support subsequent
calls to substArgTypes. typ2Itab and concatstring* don't have "any"
parameters, so no point in deep copying their function signatures at
every call site.
For a couple other syslook calls (makemap and conv[IET]2[IET]), move
them closer to their corresponding substArgTypes calls so it's easier
to see that all syslook(fn, 1) calls are necessary.
