Remove o-flag as it is redundant

Even if we extend the flag to be an n-flag with a numerical input, we
already have other Unix-tools to take care of us much more flexibly,
e.g. with head(1) you can easily get the first 10 outputs with

	slstatus -s | head -n 10,

but also e.g. discard the first one and then get the consecutive 10
outputs.

For the X11-root-window-name, you can limit the runtime with timeout(1)
or a comparable solution.

This reverts commit fa8b939990ed0648f99b0cbeba4efed807160db3.
