Fix the exit hook.

As dss_exec_cmdline_pid() uses the space character as a separator
to split the command line, the words of the error message were
passed as separate parameters to the exit hook.

Use dss_exec() directly to avoid this flaw, i.e. to pass the full
error message as $1 to the exit hook.
