I think this part should be moved to a separate package, say
"dvb-apps", on which tvheadend would depend. It can install its stuff
in $(STAGING_DIR), for example, and then you can symlink
$(@D)/data/dvb-scan of tvheadend to the right directory in
$(STAGING_DIR), or better, modify a bit tvheadend so that it can take
an argument specifying where the dvb-data is to be found.

Best regards,

Thomas
