bottles: make `or_later` the default.

When Mojave was in beta we made it so that High Sierra bottles would
automatically be used on Mojave. Let's make this the default in general:
older bottles will be used on newer versions of macOS when a newer
bottle is not available.

This should make it easier for taps to bottle single versions of bottles
which will work more widely and to give us breathing room whenever a new
version of macOS is released.

Currently this only applies to the `wine` formula which will have the
`or_later` removed in a Homebrew/homebrew-core PR.

Question: should we use an `odeprecated` for the use of `or_later`?
