libstdc++: Remove redundant diagnostic pragmas from <bits/iterator_concepts.h>

Since r16-2190-g4faa42ac0dee2c this header no longer mentions __int128
explicitly, because it's just handled like other integer types now. So
we don't need the diagnostic pragmas to disables pedwarns for referring
to __int128.

libstdc++-v3/ChangeLog:

	* include/bits/iterator_concepts.h: Remove diagnostic pragmas.
