emulators/i386-wine-devel: Style improvements

[salvadore]

Summary

• Reorder variables.
• Remove tools for updating pkg-plist: they were broken by precedent commits and based on the python 2 script files/mergeplist.py, but python 2 is now EOL.
• Move port-update target from Makefile.amd64 to Makefile and rename it distinfo-update as it does not update pkg-plist anymore.
• Remove EXTRACT_SUFX and use properly USES=tar:txz instead.
• Remove references to removed wine staging ports in CONFLICTS_INSTALL.

Tested successfully.
It only needs a mentor approval now :)

It's arguable, whether this is the right position for the options in the makefile.

Where would you put them?
I put them there trying to follow the porter's handbook's indications: https://www.freebsd.org/doc/en/books/porters-handbook/porting-order.html

My gut feeling would have put them above the block where you set the PLIST_SUBs.

But I would not lose any sleep over it :)

Committed, thanks tcberner for your comments!
