MDEV-28671 post-testing fixes

Various help message improvements:
* MySQL->MariaDB, mysqld->mariadbd, "mysqld daemon" -> "mariadbd process"
* typos
* don't specify defaults directly in the help message
* don't say that an option is deprecated, mark is as such
* missing spaces in the middle of the text
etc
