gccrs: Unit struct constructor shall be resolved

Unit struct have a special constructor that should be added to the struct
namespace in order to be resolved later when called. As it is a function
it should be added in the value namespace.

gcc/rust/ChangeLog:

	* resolve/rust-toplevel-name-resolver-2.0.cc (GlobbingVisitor::visit):
	Add the struct constructor when the struct is a unit.
