Subject: [PATCH] fix(remoteshell): give the kill option its hyphen

The fallback that runs when the restart of the ssh service fails collects the
process ids of the daemon and kills them. The option is missing its hyphen, so
the shell reads the signal number as one more process id. The daemons then get
the default signal, which a process can catch, and the shell also signals the
process with id 9.

The next line of the same fallback already uses the correct form.
