Subject: inhibit: cut off overly long "who" fields

inhibit: cut off overly long "who" fields

systemd-inhibit when invoked with a command line will put the whole
command line in the "who" field of the inhibitor lock. This can get
extremely long for shell expressions, making the table "systemd-inhibit
--list" shows ridiculously weirdly formatted. Let's put a limit on the
column width: half of the screen, not more.
