bpf: Fix bpf-next builds without CONFIG_BPF_EVENTS
This commit fixes linker errors along the lines of:
s390-linux-ld: task_iter.c:(.init.text+0xa4): undefined reference to `btf_task_struct_ids'`
Fix by defining btf_task_struct_ids unconditionally in kernel/bpf/btf.c
since there exists code that unconditionally uses btf_task_struct_ids.
