    dtrace/arm64: properly traverse the symbol table
    
    LINKER_EACH_FUNCTION_NAMEVAL() stops processing the symbol table if a
    callback function returns a non-zero value.
    
    The fbt_provide_module_function() callback should not return 1 when
    ignoring symbols. Instead, always return 0, as in dtrace/x86.
