Bug 8168: Fixing header of non CSV files for overdue notices

This determines if the CSV header should be included or not and
then generates it as needed using the delimiter specified in the
delimiter system preference.

TEST PLAN
---------
1. make some overdues books
2. run the overdue notices script without the -csv
3. check emails notice csv header is in the email
4. apply the patch
5. run the overdue notice again
6. check email notice CSV header is absent

Bug 8168: (follow-up) Use semicolon as default CSV delimiter

installer/data/mysql/sysprefs.sql has semicolon as default.
This fixes both instances to use the same fallback value.

It also prevents CSV header info from being included in non-CSV messages.

Bug 11957: reomve disused sample_only_param_tables.sql

This sql file tries to insert data into nonexistent tables.
It is useless and can be removed.

Test plan:
  git grep sample_only_param_tables
should not return any result.

NOTE: This is basically a git rm. Simple patch.

File is not used by the installers and it wouldn't work
with today's Koha for trying to insert data into non-existant
tables and tables with different structure.
