[OE-core] [PATCH v2 09/10] oeqa.utils.metadata: allow storing any bitbake config variables

[Markus Lehtonen]

Make it possible to store any bitbake config variables in the metadata.
Config values will be stored under a new config element in the xml report:
    <config>
        <variable name="MACHINE">qemux86</variable>
    </config>

The value of MACHINE is moved there instead of having a dedicated
<machine> element.
