Description:
When Executing binwalk, I get `AttributeError: module 'capstone' has no attribute 'CS_ARCH_ARM'`.
It can't execute even with --help option.

I've managed to get it work after installing `python-capstone` (3.0.4-5), I think binwalk should have python-capstone as dependency.
(I also tested that only installing `capstone 3.0.4-5` doesn't fix it)


Additional info:
* package version(s):
binwalk 2.1.1-4
python 3.6.5-3

* Here's the complete error message
```
Traceback (most recent call last):
File "/usr/bin/binwalk", line 26, in <module>
import binwalk.modules
File "/usr/lib/python3.6/site-packages/binwalk/modules/__init__.py", line 3, in <module>

Architecture(type=capstone.CS_ARCH_ARM,
AttributeError: module 'capstone' has no attribute 'CS_ARCH_ARM'
```


Steps to reproduce:
Install binwalk and execute it.
(Without installing python-capstone)

Works fine for me. Is this on Arch or Arch ARM?

The package in question is clearly marked as an optional dep already; since the package seems to function without it, I'm not seeing an issue.

After discussing with @t1016d, we found the culprit (his system was broken).
To reproduce, uninstall python-capstone and run:

# mkdir /usr/lib/python3.6/site-packages/capstone
$ binwalk

I have no idea how the directory got into his system, though.
