selftests/bpf: Add tests for bpf_throw lock leak from subprogs
Add test cases to ensure the verifier correctly rejects bpf_throw from
subprogs when RCU, preempt, or IRQ locks are held:
* reject_subprog_rcu_lock_throw: subprog acquires bpf_rcu_read_lock and
then calls bpf_throw
* reject_subprog_throw_preempt_lock: always-throwing subprog called while
caller holds bpf_preempt_disable
* reject_subprog_throw_irq_lock: always-throwing subprog called while
caller holds bpf_local_irq_save
