Build libzim & libkiwix for Android with debug symbol

[kelson42]

This is recommend by the PlayStore to be able to analyze the crash with the native code. It seems this is not the case (anymore?)

@mgautierfr Is that complicated to implement that one? We really struggle to understand Android crash happening in the libkiwix and this would be really helpful.

This seems to not be fixed, like reported by the Google PlayStore

@MohitMaliFtechiz Could you please update us here. Is that still a valid problem? I would like to nail that down considering we are on the topic of tweaking the C++ compilating/linking command line for Android.
