Android power telemetry: Update dumpsys power monitor parser to accept version 9.

Android power telemetry: Update dumpsys power monitor parser to accept version 9.

On my L-release flash, dumpsys has version number 9 now.

However, it still seems to work with the dumpsys power monitor parser, so I think we should allow it to accept 9 also.

tonyg: How good are the dumpsys power measurements? Are they suitable for doing
perf bots for android? or should the perf bots use monsoons?

They're different techniques. The dumpsys monitor gives you some signals that
correlate the CPU energy consumption. But it doesn't give you actual energy
consumption. The monsoon measures that physically. I think we'll eventually need
bots with both.

tonyg: I would be interested in starting with getting some some dumpsys Android
power bots running. Any pointers on where to get started?
