Fix (again) the run-in-cgroup.sh script

When using "sh  << EOF", what is between this line and EOF runs
with no attached terminal. But we need a terminal for running the
build. So we have to use "sh -c ". But then nesting of double
quotes, $, etc is too complicated. So run as root, and become back
user only when exec'ing. For some reason $@ does not work, so use
a variable set to $@.
