CameraService: Increase watchdog timer

- Address the frequent firing of the watchdog for disconnect() which has
often become an obstacle for debugging
- Increase default timer to a larger value of 65 seconds to prevent
thwarting of ANR error handling, since Watchdog.java triggers ANR handling after 60 seconds
- Even with the extension to a substantial duration of 65 sec, the
watchdog will retain its original intent to identify issues like
deadlocks and terminate to prevent resource consumption while preserving
existing error handling

Test: Camera CTS test; Manual trigger of watchdog
