When support was added for falling back to SMBIOS data from the kernel
in /sys/class/dmi, we inadvertently stopped caring about the data parsed
directly from DMI tables as first priority. This caused a regression in
hwids from some OEMs that relied upon IDs that could only be properly built
from DMI tables, not the kernel /sys/class/dmi interface.

Fixes: 464425fb5 ("SMBIOS: try reading from /sys/class/dmi if direct access fails")

The raw SMBIOS tables that Linux exposes in /sys/firmware/dmi
are restricted to being readable by root only. If running as
non-root access is still permitted by fields that have been
pre-parsed by the kernel in /sys/class/dmi, most of which are
world-readable. This allows the daemon to load most HWIDs even
if running as a non-root user, as is done on Chromium OS.
Until gi-docgen is declared stable support either of them.
This effectively means that hand builds and CI builds will use
gi-docgen, but distro builds use gtk-doc-tools.
This makes a lot more sense; we can parse a firmware and export the same XML
we would use in a .builder.xml file. This allows us to two two things:
* Check we can round trip from XML -> binary -> XML
* Using a .builder.xml file we can check ->write() is endian safe
