This function is useful for more than `ls` (`du` can use it too).
…t_time Removes some duplicated code, with slight, but incorrect, differences.
No need to have separate struct creation code for Windows and Unix. Also remove is_dir, we can get it from metadata.
We assume that the string has been validated by clap ahead of time (just like the current code does).
Easier to just move the change time logic to another function.
It turns out `du` used to test for the wrong thing, `ctime` is the change timestamp, not creation time. We have to rely on a regex again, as the change timestamp is the current time.

Was meant to be a maybe-not-that-useful refactoring, uncovered a bug in
du...ctimeis change time, not modification time.du/test_du: Fix ctime fallback on Windows, and test
test_du: Fix --time=ctime test
It turns out
duused to test for the wrong thing,ctimeisthe change timestamp, not creation time.
We have to rely on a regex again, as the change timestamp is the
current time.

du: Simplify Stat creation further
No need to have separate struct creation code for Windows and Unix.
Also remove is_dir, we can get it from metadata.
