chore: add mender-client-data-dir.service file

Both the mender-authd.service and mender-udpated.service files require a
mender-client-data-dir.service file. However, this isn't provided by the
mender package. This file currently resides in the meta-mender directory
under the name mender-data-dir.service.

  - Move the mender-data-dir.service file into the mender project.
  - Rename mender-data-dir.service to mender-client-data-dir.service.
  - Remove mender-client.service from "Before" and "WantedBy" as
    mender-client is now mender-authd and mender-updated respectively.
