Song Liu 3ba026fca8 x86, bpf: Use bpf_prog_pack for bpf trampoline
There are three major changes here:

1. Add arch_[alloc|free]_bpf_trampoline based on bpf_prog_pack;
2. Let arch_prepare_bpf_trampoline handle ROX input image, this requires
   arch_prepare_bpf_trampoline allocating a temporary RW buffer;
3. Update __arch_prepare_bpf_trampoline() to handle a RW buffer (rw_image)
   and a ROX buffer (image). This part is similar to the image/rw_image
   logic in bpf_int_jit_compile().
