Fix librtlsdr2 dependency chain conflict

Remove all packages that depend on librtlsdr2 before upgrading:
- dump1090-mutability (will be rebuilt from source later)
- libgnuradio-osmosdr0.2.0t64
- rtl-433 (will be reinstalled)
- librtlsdr2 and rtl-sdr

This resolves the file conflict between librtlsdr2 (2.0.1) and librtlsdr0 (2.0.2).
