Bug 25634: Warn if koha-shell returns non-zero in koha-foreach

By putting koha-shell in an if statement, "set -e" will no longer
cause the entire koha-foreach program to exit, if koha-shell
returns a non-zero status.

If a non-zero status is returned, we warn on it, and the caller
of koha-foreach can interpret that command visually.

To Test:
1) Write a shell script that says "Hello" and then exits with a 1
status
2) Run koha-foreach against that shell script with multiple instances
available to koha-foreach
3) Before the patch, koha-foreach will die after the first "Hello"
4) After the patch, koha-foreach will continue, through all the
instances, and report which instances returned non-zero statuses
by which command.
