[virt-tools-list] [libosinfo] Detection tool should set env for media ID

[Zeeshan Ali (Khattak)]

From: "Zeeshan Ali (Khattak)" <zeeshanak at gnome.org>

Detection tool now prints an environment variable 'OSINFO_MEDIA' with
the value of the ID of the media in the OS that was positively matched
against the media in question.

This implies setting of a udev property for the device by the same name.
