Small fix for _copySetConstraintsStmt

Field is a list of strings, not nodes.

Yeah, but listCopy is not the solution, because it'd only copy the cons
cells and not the pointed-to strings. The representation of
ConstraintsSetStmt is really just plain broken. It should use a list
of Value string nodes --- which would make copySetConstraintsStmt okay
as-is. Fixing now...

I fixed this by fixing the representation of ConstraintsSetStmt.
copyfuncs.c does not need to change.
