Update Commandant to 0.8.1

[ikesyo]

Resolves #309.

[norio-nomura]

I tested and got following:

% swiftlint help rules
Display the list of rules and their identifiers

[1]    8066 illegal hardware instruction  swiftlint help rules

% swiftlint help version
Display the current version of SwiftLint

[1]    7121 illegal hardware instruction  swiftlint help version

Works fine for me. Thanks @ikesyo! 🙇

@norio-nomura are you sure it's not linking a different version of a framework in your build?

Oops, I hadn't tried help, I'm also getting @norio-nomura's error. For example, running swiftlint help rules:
