    testsuite/c++: Fix lifetime of lambda in pr103953.C [PR119930]

    So in the end the problem with pr103953.C is the lifetime
    of a lambda object is not extended past the statement.
    With sane operator new we are able to delete stores using
    that object as it is dead afterwards.

    So the fix to the testcase is to make the lambda its own
    object and then call it.

    I also went back to check to make sure the original issue was
    reproducible with this version too.

    Tested on x86_64-linux-gnu and the testcase failure is gone.

    gcc/testsuite/ChangeLog:

            * g++.dg/coroutines/torture/pr103953.C: Store the second
            lambda into its own object to extend its lifeime.
