Ensure the shim APEXes have targetSdkVersion 29 at all times

When we re-built the shim APEXes with the non-finalized platform (e.g.,
R), they would again have a non-number targetSdkVersion, which will
require us to re-build them with the numbered sdk version after the SDK
finalization. To avoid that, let's fix the sdk version number fo 29
forever.

Test: mma and inspect the built APEXes
