adds executable file permissions to the cli index

for running kyt as a linked npm module

How was this working before?

We used to link to commands.js but recently added the index.js in front of that to detect Node support. After we switched, I couldn't use npm link anymore to run kyt against other projects locally. When I unlinked and linked again, npm updated the permissions and of course git marked it as a file change.

I'm not sure what the best practice is around permissions, linking and committing. The commands.js file has relaxed permissions for executing (most likely because one of us pushed it up), so I thought I'd push it this up too.

Makes sense. This seemed to fix it for me, too. So this LGTM 👍
