Android cpp dependency

As explained in official Android c++ support guide, libc++ is not a system library and it must be included in your apk if you use it.

MobileFFmpeg includes two external libraries which depend on libc++. One of them is tesseract and the other one is x265. When either of the two is enabled during compilation libc++_shared.so library is added into mobile-ffmpeg.aar archive created.

Consequently, released MobileFFmpeg packages that include tesseract and/or x265 libraries (GPL packages as of v4.2) contain libc++_shared.so library.
