Do not download transponder data as part of the build

If dvb-scan is enabled, tvheadend will download the transponders data
from the dvb-apps package. This does not play well with buildroot.

Instead, we rely on the dvb-apps package to install those files, so
it is no longer needed to install those as part of tvheadend.
