Adding the possibility to specify a test runner path besides from local ./node_modules

[moQuez]

This PR is for issue #752, I hope you guys find it useful since it is the only way I can make it work on my current project 👐

fixed a conflict with my "runnerPath" and @simonbuchan "binPath".

Not a fan of all the format diffs, though it does look like there is some mixed indentation already.

Instead of adding another property, this could instead check if the runner has a path separator (/ on posix, either / or \ on windows), and simply not path join it in that case: e.g. ./my-script is in the working dir. For windows support, you still should normalise the path to use \ - it's only required for commands run by the windows shell, but that's what's happening here.

thanks @simonbuchan, I actually removed a binPath left behind... As I submitted the PR before your's got merged I didn't resolve the conflicts properly because I was working on something else... Now everything should be fine 🙌

@simonbuchan @rotemmiz anything else that I need for this to get merged?

I'm trying to think this through, but I fail to get convinced this is valid solution. Seems like your project setup might get encountered in many issues of this type on other tools, not just Detox. I have a feeling that in your usecase it might be smarter to just add the .bin of other projects in the monorepo to your project path.
