internal/vk: [Android] add workaround for Vulkan on the emulator

Browse Source 
According to the Vulkan specification the pApplicationInfo member of
the VkInstanceCreateInfo structure may be NULL. However, the Android
emulator crashes on vkEnumeratePhysicalDevices if set to NULL.
This change adds a minimal info to please the emulator.
