Xu He Jie 2d764cb472 virsh: Add VSH_OFLAG_EMPTY_OK for attach-disk command
As the description of removing CDROM media from
  http://wiki.libvirt.org/page/QEMUSwitchToLibvirt#eject_DEV

Add flag 'VSH_OFLAG_EMPTY_OK' to the option 'source' of attach-disk

Then avoid outputting <source> in the XML if 'source' was empty,
rather than trusting libvirt domain_conf.c to understand an empty
string.
