libstdc++: Restore call to test6642 in string_vector_iterators.cc test [PR104874]

The test call was accidentally omitted in r16-2484-gdc49c0a46ec96e,
a commit that refactored this test file. This patch adds it back.

	PR libstdc++/104874

libstdc++-v3/ChangeLog:

	* testsuite/24_iterators/random_access/string_vector_iterators.cc:
	Call test6642.
