fix setting unix socket authentication on mariadb >= 10.4

[Vringe]

What does this PR do?

Quote from the MariaDB Docs:

In MariaDB 10.4 and later, the mysql.global_priv table has replaced the mysql.user table, and mysql.user should be considered obsolete. It is now a view into mysql.global_priv created for compatibility with older applications and monitoring scripts.

Example state to reproduce (A user must already exist with an other authentication plugin than unix socket):

sql_root_user:
  mysql_user.present:
    - name: root
    - host: 'localhost'
    - allow_passwordless: True
    - unix_socket: True

Previous Behavior

Salt still uses UPDATE mysql.user when changing a users authentication plugin to unix_socket. This leads to a corrupted View:

          ID: sql_root_user
    Function: mysql_user.present
        Name: root
      Result: False
     Comment: Failed to clear password for user root@localhost (MySQL Error 1356: View 'mysql.user' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them)
     Started: 15:36:08.057118
    Duration: 18.406 ms
     Changes:

New Behavior

User is altered correctly on older and newer MariaDB versions.

This will require a changelog and test coverage. We do have tests for version 10.4 so we would have caught this if the correct test was added. A good place to add the test is here: tests/pytests/integration/modules/test_mysql.py

@Vringe would you be able to loop back to this PR to add changelog and test coverage?

[Vringe]

@Ch3LL Unfortunately, I do not have the time at the moment. I tried to setup the dev environment a while ago to write and run the test but I could not get it to run properly.

@garethgreenaway @pprkut Hey guys :) i saw you both did some other work for MariaDB 10.5+ support in other issues / pr's. Any chance you can help this pr out?

[Vringe]

@cebe I saw you did some MariaDB related work for salt 3006. Unfortunately this issue still persists. Could you maybe help me out with this?
