[PATCH 0/2] MR4108: Improve DMI tables under Linux.

[eric pouech (＠epo)]

This MR improves Wine's DMI tables by:
- no longer exposing /etc/machine-id content. Current documentation
  of systemd strongly suggests to use a hash of it
  (with app dedicated key). (1)
- generates DMI entries for files that are no longer user readable
  on Linux (like bios serial number).
  The values are derived from hashed value in step #1.

(1) current implementation integrates into unix ntdll a bunch of
    sha 256 related code. It's basically a reimplementation
    of libsystemd's sd_id128_get_machine_app_specific().
    We could alternatively dynamically link to libsystemd.so.
