Bug#775424: live-build: xorriso must be called with iso level 3 to support larger live systems

[Ronny Standtke <ronny.standtke@fhnw.ch>]

Package: live-build
Version: 4.0.3-1
Severity: normal

For building larger live systems (squashfs > 4G) xorriso must be called
with iso level 3. We have been building our Debian Live based
distribution with this switch for the whole wheezy cycle and did not
notice any problem with it.

Please accept the attached patch to support larger Debian Live systems.
