configure: Don't build shell completions when disabled

With the recent changes to completion file building, the files were
built always and only installation was selectively disabled.  Now, when
they are disabled they aren't even built, avoiding a build-time error in
environments where it's not possible to run the curl binary that was
just created (e.g. if library paths were not set up correctly).
