t7001: use "ls-files --format" instead of "cut"

Since ls-files recently learned a "--format" option, we can use that
rather than asking for all of "--stage" and then pulling out the bits we
want with "cut". That's simpler and avoids two extra processes (one for
cut, and one for the subshell to hold the intermediate result).
