    libstdc++: Remove redundant -std=gnu++17 options from filesystem tests
    
    GCC defaults to -std=gnu++17 now anyway, and using it explicitly in the
    dg-options directive prevents running these tests with different modes
    such as -std=c++17 or -std=gnu++20.
    
    libstdc++-v3/ChangeLog:
