Update to Wine 5.3. This includes the following changes:

• More work towards Ucrtbase runtime support.
• Full support for Unicode normalization.
• Improvements in Shell Folders handling.
• Various bug fixes.

Also allow for this port to be used as master port for i386-wine-devel,
which means we need to avoid duplicate inclusions of bsd.port.pre.mk and
bsd.port.post.mk. [1]
