Allow passing extra flags to configure with depends builds.
[CEC] fixed - screensaver being activated sends the tv to standby, which makes the TV send another standby command. this standby command sent the PC to standby in some occasions
[CEC] increased SCREENSAVER_TIMEOUT from 10 to 20 seconds. philips sends another standby command after it's powered everything down, which takes up to 15 seconds (20 to be on the safe side)
