    Silence VLA extension warnings in fusefs tests
    
    Building tests/sys/fs/fusefs with clang 18 results the following
    warning:
    
      tests/sys/fs/fusefs/cache.cc:145:14: error: variable length arrays in C++ are a Clang extension [-Werror,-Wvla-cxx-extension]
        145 |         uint8_t buf[bufsize];
            |                     ^~~~~~~
    
    Because we do not particularly care that this is a clang extension,
    suppress the warning.
    
    MFC after:      3 days
    
    (cherry picked from commit dc0b4094abf6784bf1a9492c2fea3fb91116b014)
