[PATCH bpf-next] bpf: Fix build error in case of !CONFIG_DEBUG_INFO_BTF

[Kumar Kartikeya Dwivedi <memxor@gmail.com>]

BTF_ID_FLAGS macro needs to be able to take 0 or 1 args, so make it a
variable argument. BTF_SET8_END is incorrect, it should just be empty.

Reported-by: kernel test robot <lkp@intel.com>
Fixes: ab21d6063c01 ("bpf: Introduce 8-byte BTF set")
