Cuong Manh Le 73a4bbb0df cmd/compile: fix missing ddd when building call for function instantiation closure
When building a call expression for function instantiation closure, if
it's a variadic function, the CallExpr.IsDDD must be set for typecheck
to work properly. Otherwise, there will be a mismatch between the
arguments type and the function signature.

Fixes #49516
