[Bug libstdc++/38265] STL treats explicit constructors as converting constructors

... and I'm coming to the conclusion that this is not a bug in our library.
Consider the std::vector case: I cannot see anything wrong with using
std::uninitialized_copy in the implementation of the constructor. In turn, the
former does, per the Standard:

   ::new(static_cast<void*>(&*__cur)) typename
      iterator_traits<_ForwardIterator>::value_type(*__first);

thus, the explicit constructor can be used.
