[PATCH 3/3] Add virtio-blk support to persistent-storage rules

[Ryan Harper <ryanh@us.ibm.com>]

Using virtioblk_id add rules to extract drive serial numbers and generate
by-id links for the block device and partitions.

With these rules added, we now see the following symlinks in disk/by-id

% ls -al /dev/disk/by-id | grep vdb
lrwxrwxrwx. 1 root root   9 Jun  1 22:09 virtio-QM00001 -> ../../vda
lrwxrwxrwx. 1 root root  10 Jun  1 22:09 virtio-QM00001-part1 -> ../../vda1
