Subject: [PATCH bpf-next 07/10] bpftool: expose attach_type-to-string array to non-cgroup code

Move attach_type_strings into main.h for access in non-cgroup code.
bpf_attach_type is used for non-cgroup attach types quite widely now. So also
complete missing string translations for non-cgroup attach types.
