examples: delete unused includes

Delete a bunch of unnecessary-looking headers from some examples. This
is known to be tricky on AIX (perhaps also in other less-tested envs).

Let me know if any of this looks incorrect or outright fails on some
systems.

Follow-up to d4b85890555388bec212b75f47a5c1a48705b156 #13771
Closes #13785
