[nrf noup] ci: NCS-specific CI tweaks

Necessary changes for NCS CI.

- compliance: Add an additional check for sauce tags.
  Also, since, in the code, we refer to Kconfig symbols that are defined
  in the sdk-nrf repository, the Kconfig check will not pass. Use
  KconfigBasic instead, which will not grep the code for instances
  of CONFIG_.
- Add a Jenkinsfile.
- Extend the max commit line lengths for Gitlint.
