    libstdc++: Adjust expected locale-dependent date formats in tests
    
    The test 27_io/manipulators/extended/get_time/char/2.cc expects that
    %a in the de_DE locale is "Di" but on FreeBSD it's "Di." with a trailing
    period. Adjust the input string to be "1971 Di." instead of "Di 1971"
    and that way if %a doesn't expect the trailing '.' it simply won't
    extract it from the stream.
    
    This fixes:
    FAIL: 27_io/manipulators/extended/get_time/char/2.cc  -std=gnu++17 
execution test
    
    libstdc++-v3/ChangeLog:
    
            * testsuite/27_io/manipulators/extended/get_time/char/2.cc:
            Adjust input string so that it matches %a with or without a
            trailing period.
    
    (cherry picked from commit 4decc1062f0f6eb44209d9d5a26a744ffa474648)
