Simplify the termmode detection

As we now rely on sxmo_terminal.sh and the TERMCMD env variable, we then
can simplify things.

In the sxmo dwm context, TERMCMD="st -e" so sxmo_terminal.sh will run
the command in st.

In the ssh context, we dont have TERMCMD so sxmo_terminal.sh will just
run the command

In a tmux context, we can set TERMCMD="tmux split-window" with
set-environment -g TERMCMD "tmux split-window"
so sxmo_terminal.sh will run the command in a splited window.
