Android: Throw an error if project uses versioned shared library

Browse Source 
Android internally cannot handle versioned shared libraries.
There is no explicit rule for that, but indirect signs point to this.
This adds an explicit error to androiddeployqt to give the clear
understanding of the error nature to user. Error is also thrown if
versioned library was used when linking Qt libraries.

E.g. when linking Qt with liba.so it might be symlink to liba.so.1.0
This means that liba.so.1.0 Qt will require liba.so.1.0 at runtime.
But since Android doesn't handle versioned shared libraries,
liba.so.1.0 will never be packaged correctly. Most build systems
support generating of versionless shared libraries, and this should
be used when building 3rdparty libraries for Android.
