MDEV-24122: on previously MySQL-5.7 datadirs, adjust mysql.user column order

Browse Source 
MDEV-23201 correctly reordered columns in mysql.user table when upgrading
from MySQL-5.7

Here we also correctly reorder columns in mysql.user table from an invalid order
caused by an upgrade from MySQL-5.7 to MariaDB-before-MDEV-23201.
