When CONFIG_DEBUG_INFO_BTF is enabled and CONFIG_BPF_SYSCALL is
disabled, the following compilation error can be seen:
GEN .version
CHK include/generated/compile.h
UPD include/generated/compile.h
CC init/version.o
AR init/built-in.a

MODPOST vmlinux.symvers

LD .tmp_vmlinux.kallsyms1

'bpf_tcp_ca_kfunc_list', 'register_kfunc_btf_id_set()' and
'unregister_kfunc_btf_id_set()' are only defined when
CONFIG_BPF_SYSCALL is enabled.
Fix that by moving those definitions somewhere that doesn't depend on
the bpf() syscall.
Fixes: 14f267d95fe4 ("bpf: btf: Introduce helpers for dynamic BTF set registration")

This is RFC-ish as I don't know enough about BPF/BTF. I could be missing something.
