Update to Wine 5.13. This includes the following changes:

• Re-mapping of INI files to the registry.
• System call thunks in NTDLL.
• Reimplementation of floating point numbers printing.
• Beginnings of a restructuration of the console support.
• Various bug fixes.

A build error got in upstream the day this snapshot was created;
temporarily address this via files/patch-dlls-ntdll-unix-registry.c
which I alreadly submitted upstream.

(The Wine Staging patchset isn't yet available. No change on that
front yet - it was marked BROKEN anyway.)
