hsdis does not compile with binutils 2.34+

binutils 2.34 introduces new section flag: SEC_ELF_OCTETS, and it affects arguments of bfd_octets_per_byte() [1]. So we can see new compiler error as below:

```
gcc -o build/linux-amd64/hsdis-amd64.so -I/home/ysuenaga/rpmbuild/BUILD/binutils-2.34/include -I/home/ysuenaga/rpmbuild/BUILD/binutils-2.34/bfd -Ibuild/linux-amd64/bfd -DLIBARCH_amd64 -DLIBARCH=\"amd64\" -DLIB_EXT=\".so\" -fPIC -O hsdis.c -shared build/linux-amd64/bfd/libbfd.a build/linux-amd64/opcodes/libopcodes.a build/linux-amd64/libiberty/libiberty.a

```

We can fix it with following patch:

```
