Since 0d70656afded, it starts to access the sysfs files to build
the qemu command line (by virSCSIDeviceGetSgName, which is find
out the scsi generic device name by adpater:bus:target:unit), there
is no way to work around, qemu wants to see the scsi generic device
like "/dev/sg6" anyway.
And I think it's not only the place which needs to access sysfs
files when building qemu command line in future.
As a solution, this introduces a new argument "sysfs_root" for
qemuBuildCommandLine, and thus the tests can feed the fake sysfs
root to it.
