  Fix several vulkan backend problem on Android.
  
  * Load AHardwarebuffer API dynamically, so vulkan backend can be
    built with old NDK, but can work with newer android releases.
  * Do not link with libvulkan on android.
  * Expose EGL_ANDROID_get_native_client_buffer extension with vulkan
    backend.
