wine: move packages that depend on "wine64" binary to require "wine"

according to upstream: "The wine64 loader binary is removed, in favor of
a single wine loader that selects the correct mode based on the binary
being executed. For binaries that have both 32-bit and 64-bit versions
installed, it defaults to 64-bit. The 32-bit version can then be
launched with an explicit path, e.g. wine
c:\\windows\\syswow64\\notepad.exe.",

I have changed all the references to the wine64 binary to only need the
wine binary -- tentative.
