zsh:alias:qmv: Use destination-only edit format

Use the `destination-only` edit format when renaming files with `qmv`.

`dual-column` mode got on my nerves as I tend to forget with side is
source and which is destination. On top, the `swap` option breaks as
soon as I change the length of a filename.

`single-column` mode is useless for me, as I tend to make changes in
visual block mode.
