[PATCH v2 5/5] nodewatcher: Exit nodewatcher if subscript fails

[Fabian Bläse]

If a subscript exits with an exit status != 0, its output should not
be used. Because sending incomplete data sets might result in weird
edge cases, the nodewatcher is terminated and the output of other
subscripts is discarded.
