Bug 16830: Remove -x usage on koha-indexer

This patch just does that, and removes it from the comment on /etc/default/koha-common

To test:
- Apply the patch
- Run:
  $ vagrant ssh ; cd kohaclone
  $ sudo debian/scripts/koha-indexer --stop kohadev
  $ sudo debian/scripts/koha-indexer --start kohadev
=> SUCCESS: Verify no warning is shown on the indexer-output.log file
