 Feature patch: Reduce mythfilldatabase channel insert time (after #12685)

 While DOing the TODO in #12685 (detect a CableCARD in Ceton devices)
 is arguably the right thing to do, a side effect is that the initial
 channel insert for a Ceton device may take substantial time to complete
 (apparently the web server for a Ceton device may take 2-3 seconds to
 complete the transaction to query the CableCARD status, and for a
 (typical) 500 channel map on a cable system, that can mean delays of
 around 20 minutes during an initial mythfilldatabase run (the delays would
 likely be small in subsequent runs as there are few/no channel inserts).

 As consumer devices do not normally support CableCARD OIR, this patch
 determines the tuner unscannability once, and uses it for each channel to
 be inserted (if any).

 Initial insert time for a Ceton device is now in seconds rather than 20
 minutes (the improvement for a SiliconDust device is likely far less, as
 their devices uses a different (and much faster) process, but less network
 traffic is always better).
