Remove the calls to bpf_check_classic(), bpf_convert_filter() and bpf_migrate_runtime() and let bpf_prepare_filter() take care of that instead. seccomp_check_filter() is passed to bpf_prepare_filter() so that it gets called from there, after bpf_check_classic(). We can now remove exposure of two internal classic BPF functions previously used by seccomp. The export of bpf_check_classic() symbol, previously known as sk_chk_filter(), was there since pre git times, and no in-tree module was using it, therefore remove it. Joint work with Daniel Borkmann.
