Explore possibility of passing SafetyNet

[petefoth]

• /e/OS do it
• IodéOS do it
• FlameFire's Unofficial LOS ROM for lilac does it

Can we use one of those approaches with our builds so that they pass SafetyNet?

• Flamefire's approach: this patch: https://github.com/Flamefire/android_device_sony_lilac/blob/lineage-20/patches/make-snet-pass.patch, based on
  • https://protonaosp.org/developers/details/safetynet

    Squash of: "Spoof build fingerprint for Google Play Services" https://github.com/ProtonAOSP/android_frameworks_base/commit/14cadef1690f "keystore: Block key attestation for SafetyNet" https://github.com/ProtonAOSP/android_frameworks_base/commit/13dc7d28c12d Combined with code from: https://github.com/chiteroman/PlayIntegrityFix https://github.com/osm0sis/PlayIntegrityFork

For what it's worth, the chiteroman PlayIntegrityFix Magisk module works like a charm on my OnePlus 6 (enchilada) with your LOS21 builds. I realise the Magisk route is not what you're after, build I figured I'd mention it for reference.
