Set exit code to 0 for sa2 script shell.

Set exit code to 0 for sa2 script shell.

Hello,

we have found minor issue in sysstat. Exit code of sa2 doesn't have to be 0 even if everything is OK. This is because the last operation there is precautionary rmdir which may not have anything to do:

$ sudo sh /usr/lib64/sa/sa2 -A
$ echo $?
1

I'm attaching simple patch adding "exit 0" at the end of sa1 and sa2. What do you think?

Thanks,
