Bug 41066: Compress the APKs more

Our APK was refused by the Play Store as too big.
As a workaround, for this release we can try to compress the APK more,
by extracting it and repacking it with 7-zip.
The preferred and long-term solution would be to switch to Android App
Bundles, but this might require some changes to our signing scripts.
