RDKTV-9353: Change offline reboot threshold to 3days

Reason for change: As stability is improved doing this deadman timer
reboot is risky, so based on the discussion it changed to 3days time

Test Procedure: Keep the TV to run more than 3days based without any
reboot and see after 3days completed TV will reboot when device is in
standby state.

Risks: Low
