libstdc++: Add missing test for std::optional::transform(F&&)

The test_copy_elision() function was supposed to ensure that the result
is constructed directly in the std::optional, without early temporary
materialization. But I forgot to write the test.

libstdc++-v3/ChangeLog:

* testsuite/20_util/optional/monadic/transform.cc: Check that
an rvalue result is not materialized too soon.
