[committed] libstdc++: Remove accidental -std=gnu++17 from test

[Jonathan Wakely via Gcc-patches]

This was probably copied from a std::filesystem test and the -std option
wasn't removed.

libstdc++-v3/ChangeLog:

        * testsuite/experimental/filesystem/filesystem_error/cons.cc:
        Remove -std=gnu++17 option.

Tested x86_64-linux, committed to trunk.
