virt-manager/virtinst-nfs-install-sanitize.patch

Reference: bnc#888251
A fix for accessing nfs mounted media. A comment in the code states,
  "Convert RFC compliant NFS      nfs://server/path/to/distro
   to what mount/anaconda expect  nfs:server:/path/to/distro
   and carry the latter form around internally"
We need the RFC version to work correctly whereas redhat's anaconda
needs their own modified version.
