app-emulation/wine-vanilla: more solid wine{64,} symlink handling

To ensure potential situations where the wine binary would
be overwritten by a symlink don't happen.

Current layout worked but future changes or EXTRA_ECONF can
make it rather fragile. Only changing in 8.13/9999 given wow64
is what complexified this further.

For the record:
abi_x86_64 -abi_x86_32 -wow64 = wine64-only
abi_x86_64 -abi_x86_32 wow64 = wine-only
-abi_x86_64 abi_x86_32 -wow64 = wine-only
abi_x86_64 abi_x86_32 -wow64 = wine and wine64

Could argue that having "wine64" is not really useful, but lot of
scripts and users still expect it and other distros like Alpine are
making the symlink with wow64 too.
