and reduce the chance to be killed due to lack of memory

We'll use a different build for non-PIE < Android-16

also this build adds x86 back in

This allows any app to broadcast an Intent to Orbot in order to make Orbot
start in the background.

closes #3117 https://dev.guardianproject.info/issues/3117

When clicking on "Wizard" from the menu, then clicking back, it gets stuck
in a strange back stack purgatory, and then randomly changes the language.
So purge the wizard stuff for now, and add back the parts that are still
needed once that is all figured out.

This also simplifies the refactoring of the Intent handling.
