[Libguestfs] [PATCH 2/5] inspect: mark CoreOS /usr partitions with own USR role

[Pino Toscano]

Add a new inspect role for "/usr" partitions, and use that to mark the
/usr partition in CoreOS: this additional role allows to ease its lookup
later on, when merging its results into those of the root.
