libstdc++: Fix -Wmismatched-tags warnings for _Safe_iterator [PR120112]

This causes an ICE as shown in the PR, but it should be fixed in the
library code anyway.

libstdc++-v3/ChangeLog:

	PR c++/120112
	* include/bits/ptr_traits.h (_Safe_iterator_base): Use class
	keyword in class-head of declaration.
	* include/debug/debug.h (_Safe_iterator): Likewise.
