sxhkd: Don't start tmux by default

It turns out that since tmux sessions will stay active after you close a
terminal window, it is easy to end up with a lot of empty sessions. This
makes it difficult to detach and re-attach the appropriate tmux sessions.

Additionally, some features of kitty (notably terminal images and
dynamic background opacity) will not work inside tmux. Since kitty has
its own window manager, this caveat can be easily circumvented. By
invoking tmux manually instead, we also avoid the problem of nested
tmux sessions.
