Kleaf already generates CONFIG_UNUSED_KSYMS_WHITELIST according to the list of provided KMI symbol lists (kernel_build.kmi_symbol_list plus kernel_build.additional_kmi_symbol_lists). CONFIG_UNUSED_KSYMS_WHITELIST is the source of truth, not the wildcard here, especially if --user_kmi_symbol_list is set, or kernel_build.kmi_symbol_list or additional_kmi_symbol_lists contains files in different directories. Use CONFIG_UNUSED_KSYMS_WHITELIST directly. For mainline, CONFIG_UNUSED_KSYMS_WHITELIST is not set, so use an empty file as a placeholder.
