Add dump1090 build from source when not in repositories

On newer Debian versions (like Trixie), dump1090 isn't available
in the package repositories. Now automatically builds from the
FlightAware GitHub repo as a fallback:

- Installs build dependencies (build-essential, librtlsdr-dev, etc.)
- Clones from github.com/flightaware/dump1090
- Compiles and installs to /usr/local/bin
