Added osquery 1.0.3

This adds the new [osquery](http://osquery.io/).

The package ignores `make deps` (`tools/provision.sh`) because it justs pulls some homebrew dependencies and later calls `sudo pip install…`.

Build currently fails if Jinja2 for Python is not installed (`pip install Jinja2`).
What's the recommend way to provide the package during installation?
OK, let's re-add the OS conditional and add this issue as a TODO comment in here for someone to pick up at some point.
