Ubuntu 19.10 will be 64 bit only

Make that almost all applications. It's very unusual for a program to
have a 64-bit installer, because it won't be able to control what
happens when a user runs the installer on 32-bit Windows.

In practice, the only cases where 64-bit only wine will be useful are
when 64-bit applications are packaged some other way (such as a .zip,
Steam Play, or packaging specifically for Wine) or for running Wine
builtins like msidb.
