V2 podman system service

* Added support for system service
* Enabled linting on the varlinkapi source, needed to support V2
  service command
* Added support for PODMAN_SOCKET

Skip linting deprecated code

Rather than introduce bugs by correcting deprecated code, linting the
code is being skipped. Code that is being ported into V2 is being
checked.
