Remove LiveWallpapersPicker from ATV emulator

This is not installed on our reference designs and there is no good
reason to have it present on stock Android TV.

As always, Downstream devices may want to include this for specific
usecases, but default assumption when developing for generic Android
TV is that there will be no UI to choose a live wallpaper.

Test: lunch atv_google_x86-userdebug ; make sdk -j30 ; emulator
