sig spoofing: extend with PackageInfo.signingInfo / various Google Apps stop working with microG

[steadfasterX]

Reproduction steps / Problem description

issue:

Google seemingly has updated their signature checking code. On Android 9 and above, the latest code uses PackageInfo.signingInfo (via GET_SINGNING_CERTIFICATES flags) instead of PackageInfo.signatures (via GET_SIGNATURES flag). This will likely roll out to non-Google apps in the future as well.

This means that all signature spoofing patches need to be updated to address the change of API usage by - in addition to the PackageInfo.signatures also spoofing the PackageInfo.signingInfo. There's unfortunately nothing we can do in microG itself.
