libstdc++: Simplify std::allocator_traits<allocator<void>>::construct

Browse source 
We don't need a preprocessor condition to decide whether to use
placement new or std::construct_at, because std::_Construct already does
that.

libstdc++-v3/ChangeLog:

	* include/bits/alloc_traits.h (allocator_traits<allocator<void>>):
	Use std::_Construct for construct.
