1. btf,info: Fix bad instruction offset when parsing infos from kernel …

   When BTF ext info is encoded in ELF the instruction offsets are in
   bytes, but when you pass them to the kernel they must be instruction
   indices. Therefore we divide the offset by the instruction size in
   the parsing logic for ELF.
   
   This was missed during the initial implementation of reading back BTF
   ext info from the kernel. This would cause an error when loading
   back ext info which was not a multiple of the instruction size or
   a bad instruction offset if it was.
   
   Fix this by making LoadLineInfos and LoadFuncInfos work on the kernel
   format which contains instruction offsets while the ELF parser uses
   bytes instead.
