my_snprintf fixes for 10.6+

MDEV-21978 found many erroneous my_snprintf formattings when it reenabled GCC printf checks.
Patches to these errors should apply to the oldest applicable version in maintenance and up.

In MariaDB 10.6 and up, the following strings may display their fields corrupted depending on the compiler and platform:

• (DBUG) print_admin_msg: <name>, <Op. name>, <type>, <message> (Op. name and <type> print incorrectly)
• (DBUG) xid: <undefined> xid (<undefined> not filled in with xid)
• InnoDB: Index root page <ID> in <name> is corrupted at <undefined> (<undefined> not filled in with the offset) (from MDEV-13542)
• InnoDB: Failed to load tablespace <ID> for table <name>
• (DBUG) Files : <count> (big-endian CPUs only?)
• and MDEV-34799
