Set the buffer to the code in the BPF linear info. This enables BPF JIT code disassembly by LLVM and capstone. Move the common but minimal disassmble_bpf_image call to disassemble_objdump so that it is only called after falling back to the objdump option. Similarly move the disassmble_bpf function to disassemble_objdump and rename to disassmble_bpf_libbfd to make it clearer that this support relies on libbfd.
