Change the value of `pathlib._abc.PurePathBase.pathmod` from `os.path` to `posixpath`. User subclasses of `PurePathBase` and `PathBase` previously used the host OS's path syntax, e.g. backslashes as separators on Windows. This is wrong in most use cases, and likely to catch developers out unless they test on both Windows and non-Windows machines. In this patch we change the default to POSIX syntax, regardless of OS. This is somewhat arguable (why not make all aspects of syntax abstract and individually configurable?) but an improvement all the same. This change has no effect on `PurePath`, `Path`, nor their subclasses. Only private APIs are affected.
