Make std::os::unix/linux::fs::MetadataExt::a/m/ctime* documentation clearer

I was confused by this API so I clarified what they are doing.

I was wondering if I should try to unify more documentation and examples between `unix` and `linux` (e.g. “of the file” is used in `unix` to refer to the file these metadata is for, “of this file” in `linux`, “of the underlying file” in `std::fs::File`).
