Bug 15011: koha-indexer should define the --pidfiles on starting the daemon

The --pidfiles options is not provided on starting the daemon and the is_indexer_running consider that the daemon is not running

Test plan:
koha-indexer start
koha-indexer stop

should start and stop the zebra daemon wuthout any error.

Signed-off-by: Tomas Cohen Arazi <tomascohen@theke.io>
Tested on kohadevbox:ansible

sudo debian/scripts/koha-indexer --stop kohadev
sudo debian/scripts/koha-indexer --start kohadev
sudo debian/scripts/koha-indexer --restart kohadev

All work as expected on the different scenarios.
