Hdd build fails in syslinux stage

[WillDyson]

In version live-build_3.0~a57-1ubuntu4, trying to build a hdd image with mode=ubuntu and a syslinux theme with a static live.cfg fails with:

sed: can't read /live.cfg: No such file or directory

ubuntu-casper-normalisation.patch adds a line that tries to alter ${_SUFFIX}/live.cfg, but _SUFFIX is undefined. ${_TARGET}/live.cfg should be used instead.

Patch attached.
