Subject: [PATCH] util: Add "shareable" field for virSCSIDevice struct

https://bugzilla.redhat.com/show_bug.cgi?id=957292

Unlike the host devices of other types, SCSI host device XML supports
"shareable" tag. This patch introduces it for the virSCSIDevice struct
for a later patch use (to detect if the SCSI device is shareable when
preparing the SCSI host device in QEMU driver).
(cherry picked from commit 2b66504ded244a249aa4a877b41c1ef9101ba28f)
