Richard Hughes 0c51630991 Check firmware magic in a more standard way 
Some parsers are ignoring the magic when using _FLAG_IGNORE_CHECKSUM
(which is wrong; fuzzers have no problem with enforcing a static prefix)
and other either disregard the offset or check the magic in an unsafe
way. Also, use FWUPD_ERROR_INVALID_FILE consistently for magic failure.

Add a vfunc, and move all the clever code into one place.

Platform Health Assessment Table

Introduction

The PHAT is an ACPI table where a platform can expose health related telemetry that may be useful for software running within the constraints of an OS.

These elements are typically going to encompass things that are likely otherwise not enumerable during the OS runtime phase of operations, such as version of pre-OS components.

The daemon includes some of the PHAT data in the report data sent to the LVFS so that we can debug failures with the help of the IHV. This allows us to find the root cause of the problem, and so we know what other OEMs may be affected.

See https://uefi.org/htmlspecs/ACPI_Spec_6_4_html/05_ACPI_Software_Programming_Model/ACPI_Software_Programming_Model.html#platform-health-assessment-table for more information.
