fix: use stdin=inhert on vanilla run

* fix: non-utf8 stdin processing
Fixes #890
Ref FormidableLabs/webpack-dashboard#16

The library blessed inside of the webpack-dashboard does some funky stuff with std streams and the expectation of the encoding. I'm not 100% sure of this change, I've got to see all the tests, but this tweak moves to inherit the child's stdin and doesn't purposely encode the stdin stream as utf8 (which, I don't recall exactly why I did this in the first place…though I'm fairly sure it was another issue somewhere else in nodemon).
* fix: use stdin:inherit when we're not forked
* fix: don't use inherit when required
* style: lint
* style: I am going to 🐎 kick the lint in the 🌰
