Jiri Olsa 789bd77c93 bpf: Set run context for rawtp test_run callback
[ Upstream commit d0d1df8ba1 ]

syzbot reported crash when rawtp program executed through the
test_run interface calls bpf_get_attach_cookie helper or any
other helper that touches task->bpf_ctx pointer.

Setting the run context (task->bpf_ctx pointer) for test_run
callback.

Fixes: 7adfc6c9b3 ("bpf: Add bpf_get_attach_cookie() BPF helper to access bpf_cookie value")
