sched_ext: add CONFIG_DEBUG_INFO_BTF dependency 



Without BTF, attempting to load any sched_ext scheduler will result in
an error like the following:

  libbpf: kernel BTF is missing at '/sys/kernel/btf/vmlinux', was CONFIG_DEBUG_INFO_BTF enabled?

This makes sched_ext pretty much unusable, so explicitly depend on
CONFIG_DEBUG_INFO_BTF to prevent these issues.
