* This avoids EuiccGoogle / GoogleCarrierServices crashing, taking the
whole telephony stack with them when no GMS or GSF is installed.
* Compared to change 274251, this approach is no-op when GAPPS add-on is
flashed before the first boot, and thus should not cause issues with
eSIM when GAPPS is flashed.
* With microG, this also works after installing the microG GMS & GSF
packages and rebooting, although manual activation of the eSIM is
needed via Settings - Network.
* The only downside is that users will still see one or two crashes
during the first boot because our application only starts after the
device is booted.
