From: Vicente Olivert Riera @ 2015-10-13 10:18 UTC (permalink / raw)
  To: buildroot

The content of the saned.socket and saned at .service files is based on the
instructions of the sane-backends manual.

Signed-off-by: Vicente Olivert Riera <Vincent.Riera@imgtec.com>
---
Changes v2 -> v3:
  - Create the "target.wants" directories for the socket and the service
    and put symlinks in there pointing to the real files. (Suggested by
    Maxime Hadjinlian)

Changes v1 -> v2:
  - Install the systemd files in /usr/lib/systemd/system. (Suggested by
    Maxime Hadjinlian)
  - Create saned user and group (Highlighted by Maxime Hadjinlian)
  - Amend the commit log since we are not using the location for the
    systemd files specified in the manual.
