Implement switch to keep extractNativeLibs manifest option

[basilgello]

Introduce the CLI option to preserve android:extractNativeLibraries to allow re-packing apps that initially ship with this setting (and some code relies on it!)

To repack such an application with apktool successfully, one needs to:

• put shared library extension (so) to doNotCompress section of apktool.yml in the decompiled app directory:

  doNotCompress:
  - so
  

• build APK back using apktool b

• zipalign using the zipalign tool from latest Android SDK:

  zipalign -p -f 4 app-rebuilt.apk                                                                                  
  

• sign APK by apksigner or uber-apk-signer skipping its own zipalign step:

  java -jar uber-apk-signer --skipZipAlign
