Also need to change references of mariadb_safe to mariadbd-safe in man/mysqld_safe.1

I wasn't sure if I should change the man pages because mariadb_safe still works, but I think it's better. Thanks.

Yes mariadb_safe works, but it is deprecated, so I think removing it from the man is safe. If you could add mariadbd-safe as well to what you have done, I think this is in a good place.

Hi @LinuxJedi, thanks for the clarifications. I also added mariadbd-safe to the man page.

Many thanks for fixing that.
