libstdc++: Fix some -Wsign-compare warnings in the testsuite

libstdc++-v3/ChangeLog:

	* testsuite/23_containers/unordered_map/modifiers/reserve.cc:
	Cast to size_t to fix -Wsign-compare warning.
	* testsuite/23_containers/unordered_set/hash_policy/71181.cc:
	Likewise.
	* testsuite/23_containers/unordered_set/insert/move_range.cc:
	Likewise.
