emulators/wine: Invoke with LD_BIND_NOW and revampe WoW

Wine 6.0 and later need LD_BIND_NOW / LD_32_BIND_NOW on FreeBSD,
cf. https://bugs.winehq.org/show_bug.cgi?id=50257 and
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=252307
so move the actual binaries to wine64.bin / wine.bin and invoke
them via a script that does those settings.

Also revamp the WoW handling/packging which combines 32-bit/i386
Wine into 64-bit/amd64 Wine.
