lash_wrap never exits (fix included)

Binary package hint: lashwrap

$ lash_wrap -- sleep 3600
$ killall sleep
$ sleep 5; pidof lash_wrap
10234

lash_wrap doesn't exit when the wrapped application terminates, because it improperly tries to ignore SIGCHLD. From the waitpid manpage:

Note that even though the default disposition of SIGCHLD is "ignore", explicitly setting the disposition to SIG_IGN results in different treatment of zombie process children.

The fix is simple -- remove the line that says

signal(SIGCHLD, SIG_IGN)

It's unnecessary and it harmful.
