zprofile: Use exec when attaching to tmux

Browse Source 
When connected over ssh and attaching to/creating a tmux session, the
shell should `exec` the tmux command so that detaching from the session
automatically also closes the ssh connection.

If something should happen and the `tmux` command bricks the remote
shell this can fixed by logging in with:

    ssh [destination] zsh -dfi
