Subject: [PATCH] std.Io.Dir: fix incorrect return types in setFileOwner and
 setTimestampsNow

`setFileOwner` declared `SetOwnerError!void` but its vtable method
returns the wider `SetFileOwnerError!void` (adds `NameTooLong` and
`BadPathName`), so any call through the wrapper fails to compile.

`setTimestampsNow` dispatched to `io.vtable.fileSetTimestamps` with
`(Dir, []const u8, Dir.SetTimestampsOptions)`, but that vtable entry
takes `(File, File.SetTimestampsOptions)`. The intended target is
`dirSetTimestamps`, whose signature matches the call site.
