Alexandre Macabies f816402fd0 rtl-sdr: use hardened udev rules
rtl-sdr latest release 0.6.0 is from 2018. Six months ago master received
a patch[1] to use improved udev rules that chown to plugdev instead of
making the devices world-read-writable.

This change backports [1] as an upstream patch.

# /etc/udev/rules.d/, and there is no option to install elsewhere. So install
# rules manually.
# * Propagate libusb-1.0 dependency in pkg-config file.
