[BUGFIX] Unbork remote helper execution

Someone that obiviously didn't test the change did the following (the
code blames to me, but I didn't write this):

code = start_command(helper);
if (code < 0 && errno == ENOENT)
	die("Unable to find remote helper for '%s'", data->name);
else
	exit(code);

Which is obiviously wrong. The code shouldn't exit if code is 0.
