reftable: make REFTABLE_UNUSED C99 compatible
Since f93b2a0424 (reftable/basics: introduce `REFTABLE_UNUSED` annotation, 2025-02-18), the reftable library was migrated to use an internal version of `UNUSED`, which unconditionally sets a GNU __attribute__ to avoid warnings function parameters that are not being used. Make the definition conditional to prevent breaking the build with non GNU compilers. Reported-by: "Randall S. Becker" <rsbecker@nexbridge.com> Signed-off-by: Carlo Marcelo Arenas Belón <carenas@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
