Followup Bug 9353: Missing subfields on MARC21 frameworks

This followup changes updatedatabase.pl.
Only touch frameworks that have the missing subfields.

If both patches are applied, the test plan changes.

To test:
1) dev master system with default and example MARC21 frameworks
2) Go to Home > Administration > MARC frameworks
3) Click on 'MARC structure' of any framework
4) Search for tag 029 (or 863/4/5)
5) Click 'Subfields', there are none.
6) Apply both patches
7) run 'perl installer/data/mysql/updatedatabase.pl'
8) Repeat steps 2-4
9) Click 'Subfields', now they are.

Update works nicely. Checked various frameworks and
results were ok. Also new fields are hidden.
