QFlightInstruments README misleading / incomplete

`README.md` file for QFlightInstruments states that:
> The building proccess will generate a debian package, so you can deploy wherever you want.

But no deb file is generated inside QFlightInstruments path after issuing any of the standard `make` commands.

Also, the `README.md` file has a section called _Make Package_ which tells to use `make package debuild -uc -us`. This command results in error in error in all forms (either running `make package` alone, `debuild -uc -us` alone, or the complete command).
