[Telemetry] Speed up page_cycler on android.

Down to 3m22 (without the other optimizations..)
/proc/pid/smaps is kind of large.
It was only used by old style perf tests downstream, long gone
in favor of Telemetry.
Use "showmap %pid" directly, which crunches the data in the device.
Also, while at it, remove GetMemoryUsageForPackage: no longer used.
