This pulls in a fix for Android, where Android's seccomp policy on older versions is to make `openat2` irrecoverably crash the process, so we have to do a version check up front rather than relying on `ENOSYS` to determine if `openat2` is supported. And it pulls in the fix for the link errors when multiple versions of rsix/rustix are linked in. And it has updates for two crate renamings: rsix has been renamed to rustix, and unsafe-io has been renamed to io-extras.
