[PATCH] Bug #45868 DVD: Fix isolinux.cfg parsing

[Philipp Hahn <hahn@univention.de>]

Debian added Multi-Arch support to its CD images, where "label" and
"append" have to be special parsed to distinguish between "ifcpu64" and
normal "linux" statements.

That broke "append" parsing, as those lines were no longer passed on for
further procession:
> 162: foreach my $line(@lines) {
...
> 239    } elsif ($line =~ /append (.*)$/ && $in_kernel) {
> 240        $kernel{"append"} = $1;
no longer trigger.

Pass on the line if we are not in "ifcpu64==3" mode.
