rtl-sdr: Install tweaked udev rules

To enable agl-service-radio to access the RTL-SDR USB devices, install
the provided rtl-sdr.rules file in /etc/udev/rules.d, modifying it to
tweak the device permissions, group, and SMACK label to meet the
requirements for the new application framework audio permission.
