Start the lakitu kernel's revision at 1, instead of -r0.

Without this we get:

```
 * ERROR: sys-kernel/lakitu-kernel-5_15-5.15.161-r0::project-edgeos failed:
 *
 * Failed Generating Licensing for sys-kernel/lakitu-kernel-5_15-5.15.161-r0
 * Note that many/most open source licenses require that you distribute the license
 * with the code, therefore you should fix this instead of overridding this check.
 *
 * Note too that you need to bundle the license with binary packages too, even
 * if they are not part of ChromeOS proper since all packages are available as
 * prebuilts to anyone and therefore must include a license.
 *
 * If you need help resolving the licensing error you just got, please have a
 * look at
 * https://dev.chromium.org/chromium-os/licensing/licensing-for-chromiumos-package-owners

```

- This is due to the way version strings are treated:
  https://cos.git.corp.google.com/third_party/chromite/+/refs/heads/main/licensing/licenses_lib.py#337
  The package version parser treats no revision as revision zero, and
  vice-versa. So when we set the version name to -r0, it parses it and
  then stringifies it back and then when it compares the two to ensure
  it parsed correctly, it fails.

  Revbumping to -r1 makes it work.
