libstdc++: Tweak common_iterator::operator-> return type [PR104443]

This adjusts the return type to match the resolution of LWG 3672. There
is no functional difference, because decltype(auto) always deduced a
value anyway, but this makes it simpler and consistent with the working
draft.

libstdc++-v3/ChangeLog:

	PR libstdc++/104443
	* include/bits/stl_iterator.h (common_iterator::operator->):
	Change return type to just auto.
