ndk-sys: Bump version to latest-published 0.4.1+23.1.7779620

This again makes it possible to `patch` the latest `ndk-sys` crate used
in a dependency tree.  There are no backports from `0.4.0` -> `0.4.1`
and this version metadata was not matching the NDK version the crate is
generated from anyway to prevent the CI from releasing the same crate
version again with different version metadata (which results in `cargo`
errors locally, yet crates.io still allows uploading such a conflict:
#369 (comment)).
