Because systemd did something obnoxious, the kernel retaliated in the
game of Core Wars by hiding all arguments before `--' from userspace.
So use `---' instead so that all the arguments remain visible.

This in some sense now applies to host installs a change we had
already made to Debian HVM guests.  See osstest#493b7395
  ts-debian-hvm-install: Use ---, and no longer duplicate $gconsole
and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=762007
  Kernel command line handling change breaks d-i user-params functionality

This change is fine for all non-ancient versions of Debian, so I have
not made it conditional.
