Migrate universal apks to split apks

We have auto update support for multiple build blocks now. So we should migrate those apps with native libs to split apps:

1. Apps already have multiple build blocks for every version and updated manully;
2. Apps have all abis and pretty large;
3. Apps only have armv7 abi in F-Droid;

Difficulties:

Many apps support split abis but we need to patch the code to build one abi one time. Some apps has strange version code scheme that can be handled by fdroidserver well.

https://developer.android.com/google/play/publishing/multiple-apks#VersionCodes We need to ask devs providing a version code scheme for different abis.
