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?
Can this test be modified to do something more substantial than e.g. `--version` or `--help`? See `cmake.rb` for an example of an application formula with a good test and `tinyxml2.rb` for an example of a library formula with a good test. Thanks!
