dwm-status: Remove wrong comment

It simply doesn't work. Bash doesn't read the whole file at once. So,
when lines are inserted above the "sleep 10", things break apart.

Running sleep and exec in a forked subshell could work better (this
subshell inherites the session id of my xinitrc, so dwm-status is still
killed when I quit dwm -- that's what I want). It's still not correct,
though: When saving the script while it's NOT sleeping, it breaks.
