[Telemetry] Cut down on the amount of log spam on the android perf bots.

The perf bots run with -v (INFO level debugging). I'm moving the noisiest
output to DEBUG level. This will make the android log output more parsable
so that the real failures are easier to spot.

Also, this cuts down on several commands running between each page.

BUG=None
TEST=smoothness and page_cycler on android
