Subject: [PATCH 1/2] libs/utils/android: add initial support for system
 utilities

The Android::System module is meant to collect functions related to system
tunables. For the time being we add just one function which allows to
toggle the AIRPLANE mode of an Android target.

Subject: [PATCH 2/2] libs/utils/android: ensure Jankbench is executed while in
 AIRPLANE mode

We do not need WiFi connectivity while Jankbench runs thus, to have more
stable measurements for energy consumption, let's enabled AIRPLANE mode
before starting the test.
