Subject: [PATCH] realtime script:  Fix RTAPI unload detection in Jessie

In Stretch and Buster, output formats may be combined with commas:

    $ ps -p 1 -o pid=,s=
        1 S

On Jessie, this does not work:

    $ ps -p 1 -o pid=,s=
      ,s=
        1

But separating them as separate options does:

    $ ps -p 1 -o pid= -o s=
        1 S

This patch fixes e.g. `rtapi:0` exit detection in the `realtime`
script, a problem introduced by YT in 61446ef4.

Fixes #164.
