Subject: [PATCH] libstd: handle rmdirZ INVAL error (#10145)

The INVAL error was marked unreachable which prevents handling
of the error at a higher level.

It seems like it should map to BadPathError based on the man page for
rmdir (and an incomplete understanding of DeleteDirError), which says:

```
EINVAL pathname has .  as last component.
```
