Bug 34653: Make koha-foreach return the correct status code

I think the correct behavior for this script should be that koha-foreach
will return 0 (success) if all the commands it tried to run succeeded, but
1 (failure) if any of the commands failed.

To test:
1. $ koha-create --create-db test
2. $ vi test.sh
if [ $USER = 'kohadev-koha' ]; then
    echo "FAILED";
    exit 1;
else
    echo "SUCCESS";
    exit 0;
fi

3. $ debian/scripts/koha-foreach sh test.sh
FAILED
kohadev: 1 status returned by "sh test.sh"
SUCCESS
4. $ echo $?
5. Note that the exit status is 0 (success)

6. Apply patch

7. $ debian/scripts/koha-foreach sh test.sh
FAILED
kohadev: 1 status returned by "sh test.sh"
SUCCESS
8. $ echo $?
9. Note that the exit status is 1 (failure)
