Silence VLA extension warnings in fusefs tests

Browse source 
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
