selftests/bpf: test struct_ops with epoll
Verify whether a user space program is informed through epoll with EPOLLHUP when a struct_ops object is detached. The BPF code in selftests/bpf/progs/struct_ops_module.c has become complex. Therefore, struct_ops_detach.c has been added to segregate the BPF code for detachment tests from the BPF code for other tests based on the recommendation of Andrii Nakryiko.
