    Use generated func names directly for test output
    
    G_STRFUNC can produce slightly different output on each compiler, eg
    function names under GCC, and full function signatures on clang.
    
    Instead of using G_STRFUNC for output, we store the generated function
    name from buffer-tests.inc in a macro for each test and print that.
