Upgrade misc/udfclient to version 0.4.5

UDFclient.0.4.5 : serious cleanup and bugfix release fixing serious `mkdir'
brokenness and introducing a more decent logical volume open/close
behaviour with coupled logical volume integrity sequence support that was
lacking. Discs opened read-only are now really read-only; one could delete
files from a read-only disc that could result in broken discs.
