Remove ndk_platform backend. Use the ndk backend.

The ndk_platform backend will soon be deprecated because the ndk backend
can serve the same purpose. This is to eliminate the confusion about
having two variants (ndk and ndk_platform) for the same ndk backend.

The prebuilt files had a reference to
android.hardware.gnss-V1-ndk_platform.so. Change it to
android.hardware.gnss-V1-ndk.so by diretly editing the DT_NEEDED entry.
