Subject: [PATCH] MT#55881 diff/15301.up: rename offset variable to support
 MariaDB >=10.6

Fixes:

| Applying revision script /usr/share/ngcp-db-schema/db_scripts/diff/15301.up: ERROR 1064 (42000) at line 14: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'offset int;
|     DECLARE chunk longblob;
|     DECLARE done int DEFAULT FALSE;
|
| ...' at line 4
| failed. :(

This is caused by MariaDB having "offset" as reserved word, quoting from
https://mariadb.com/kb/en/upgrading-from-mariadb-10-5-to-mariadb-10-6/:

| New reserved word: OFFSET. This can no longer be used as an identifier without being quoted.

Now that Debian/bookworm includes mariadb-server v10.6.10-1
we need to rename the variable.
