    libstdc++: Fix test to use correct function
    
    This was copied from a test for std::lcm but I forgot to change one of
    the calls to use the experimental version of the function.
    
    libstdc++-v3/ChangeLog:
    
            PR libstdc++/92978
            * testsuite/experimental/numeric/92978.cc: Use experimental::lcm
            not std::lcm.
