Fix feature set of low-ram configuration of AndroidTV

Despite the fact that the multiscreen is disabled on low_ram, AndroidTV
shows picture_in_picture and activities_on_secondary_displays in the
available feature set (adb shell pm list features). It causes some
applications to crash when enter PIP functionality because
PackageManager.hasSystemFeature returns true (should be false) on
low_ram configuration.

Test: manual test - try to run application (Live Channels & VLC) in PIP before and after change.
