bpf: Remove bpf_image tree
Now that we have all the objects (bpf_prog, bpf_trampoline, bpf_dispatcher) linked in bpf_tree, there's no need to have separate bpf_image tree for images. Reverting the bpf_image tree together with struct bpf_image, because it's no longer needed. Also removing bpf_image_alloc function and adding the original bpf_jit_alloc_exec_page interface instead. The kernel_text_address function can now rely only on is_bpf_text_address, because it checks the bpf_tree that contains all the objects. Keeping bpf_image_ksym_add and bpf_image_ksym_del because they are useful wrappers with perf's ksymbol interface calls.
