app-emulation/podman: Update podman to use new RESTful API service pl…

…us New Features

  podman varlink is deprecated in the v2 release

  CHANGES:
  1) Update Copyright date (Hello 2021)
  2) s/varlink/system service/
  3) Use the default unix socket path:  unix:/run/podman/podman.sock

  NEW FEATURES:
  1) Config --log-level.  Using 'debug' as the default level is a bit noisy.
  2) Config listening socket.
  3) Config user[:group] to run daemon as for rootless services.

  The new Config options allow for symlinking off the primary service to
    start multiple daemons for rootless API services.
    e.g. ln -s podman podman-terra
