MDEV-23009 SIGSEGV in get_field from acl_load (on optimized builds)

Browse Source 
Classes that handle privilege tables (like Tables_priv_table)
could read some columns conditionally but they expect a certain
minimal number of colunms always to exist.

Add a check for a minimal required number of columns in privilege tables,
don't use a table that has fewer columns than required.
