Update to ndk-glue 0.7.0?

[torokati44]

According to the compatibility table at https://github.com/rust-windowing/winit#android, to work with winit, ndk-glue should be either 0.5.0, or 0.7.0.
The fact that oboe-rs depends on ndk-glue 0.6.0 causes some compatibility issues.
So, would it be possible to update the ndk-glue dependency to be on 0.7.0?

Well, oboe-rs might only directly depend on ndk itself, not ndk-glue, but the version issue is the same.

Fwiw most important is the ndk upgrade to 0.7.0, ndk-glue is just used to get an Android Activity in the demo.
