Android: Remove unusable android_stl=no option

As of 3.1 and later, we have too many thirdparty C++ dependencies
and some internal uses of `new` and `delete` too for it to make
sense to build without the STL on Android.

The option has been broken since 3.0, and the "System STL" that we
relied on for basic support of `new` and `delete` is likely to be
dropped from the NDK:
