Capstone update breaks ropgadget

[pmondon]

Capstone has been updated to 6.0.0a1, subsequently, pwntools isn't working (see bellow). A working patch for me is to downgrade capstone to 5.0.3

This only breaks when trying to load rop gadgets for aarch64 binaries btw. We only test for x86, which is why this didn't trigger in CI. I don't think the ROP class properly supports anything but x86/x86_64 too.
