Fix touch to allow changing timestamps on directories, remake from #11760

[kik4444]

Based off of #11760 to be mergable without conflicts.

Description

Fix for #11757.
The main issue in #11757 is I tried to copy the timestamp from one directory to another only to realize that did not work whereas the coreutils ^touch had no problems. I thought --reference just did not work, but apparently the whole touch command could not work on directories because OpenOptions::new().write(true).create(true).open(&item) tries to create touch's target in advance and then modify its timestamps. But if the target is a directory that already exists then this would fail even though the crate used for working with timestamps, filetime, already works on directories.

User-Facing Changes

I don't believe this should change any existing valid behaviors. It just changes a non-working behavior.

Tests + Formatting

I only could not run cargo test because I get compilation errors on the latest main branch
All tests pass with cargo test --features=sqlite
