v0.36.0 on v6.18: bindsnoop - error: invalid application of 'sizeof' to an incomplete type 'struct bpf_task_work'

Release v0.36.0 fails to run `bindsnoop` Python tool it provides on Linux 6.18.7 which it supposed to support:

```

Reproduce the failure by running the provided bindsnoop command on Linux 6.18.7, then inspect the generated BPF source and the referenced include/linux/bpf.h definitions. Trace how bindsnoop reaches the incomplete bpf_task_work type and verify that the tool compiles and starts successfully on the reported kernel.
