fix Issue 22102 - importC: Error: function is used as a type

[ibuclaw]

If a declaration looks like a function call, assume it is one. If during semantic, the callee is resolved as a type-name, rewrite the expression as a declaration or issue an error because C does not have type construction syntax.
