Bug 9256 - Fix search for the packages

See the bug for a description of the problem.

This patch tries to restore searching for marcflavour != MARC21 as well as
allowing instances with different marcflavors to co-exist on the same server.

To test:
- Do a package install with e.g. the official squeeze-dev packages and create at
  least two instances, with different marcflavours, e.g.:
  sudo koha-create --create-db --marcflavor marc21 test1
  sudo koha-create --create-db --marcflavor normarc test2
- Run through the web installers for both instances and add a couple of
  records to each. Wait for the records to be indexed or run indexing manually
  with
  sudo koha-rebuild-zebra -f test1
  sudo koha-rebuild-zebra -f test2
- Try searching for the records you added. It should work in test1 but not in
  test2.
- Apply the patch and build packages with the build-git-snapshot script
- Install the new koha-common package
- Create two instances (because of Bug 9754 it is probably best to give the
  instances different names than the ones you created above, or to do this on
  a fresh VM or similar) and add records, as described above. Searching should
  now work equally well for both instances.

Please note: Because of Bug 9752 you will have to set marcflavour = NORMARC
by hand before you do the searching, if you choose NORMARC as the marc flavour
on one of the instances you create.

Please note too: I am not confident that this is the perfect solution, so
merciless and thorough testing is necessary! ;-)

Works for me for GRS-1 (package installation out of the box). Could not figure out how to set up DOM indexing and eventually stopped caring about it.

Build packages with the patch and checked that creating
instances and search within them works for both MARC21 and NORMARC.
All tests and QA script pass.
