perfetto/android: align datasource names with tooling expectations

A few Android tools are based on/assume the datasource names
gpu.renderstages and gpu.counters. It is less effort to align with that
naming for Android builds than to chase down those tools and fix them,
not to mention account for new tools that may be created in the future.
