iso build broken

[jpryzby+d at quoininc.com (Justin Pryzby)]

Hi Everyone,

I had to apply this patch to get my 2-kernel-debs ISO build to work;
otherwise the mv fails due to "file not found".  I don't know all of
what the intended changes of lh_binary_syslinux are supposed to do
(besides reducing code) so this may not be a real fix.  My kernels
files were already named {vmlinuz,initrd}[12].
