fix(xtask): Use --package instead of -p on cargo ndk.

We use `cargo ndk -p {package_name}`, where `-p` is short for
`--package`. However, `cargo ndk` has introduced the `-p` option (see
bbqsrc/cargo-ndk@c6b93a8),
short for `--platform`. It creates a confusion and the command line
doesn't execute properly. Let's use the long option `--package` to
clarify everything.
