libstdc++: Remove redundant macro that is always empty

The __iter_swap class template and explicit specialization are only
declared (and used) for C++03 so _GLIBCXX20_CONSTEXPR does nothing here.

* include/bits/stl_algobase.h (__iter_swap, __iter_swap<true>): Remove
redundant _GLIBCXX20_CONSTEXPR.
