For non-root installation, the mcsmysql alias needs to be set to use the non-root user

Build tested: 1.4.0-1

[guest@localhost ~]$ cat gitversionInfo.txt

The mcsmysql alias is always set to use the root SQL user. This is no longer allowed by default in 1.4.0-1 (server 10.4.7-2). the SQL user needs to be set to the current non-root user, which is guest in my test

[guest@localhost ~]$ mcsmysql
ERROR 1698 (28000): Access denied for user 'root'@'localhost'
[guest@localhost ~]$ alias mcsmysql
alias mcsmysql='/home/guest/mariadb/columnstore/mysql/bin/mysql --defaults-extra-file=/home/guest/mariadb/columnstore/mysql/my.cnf -u root'
[guest@localhost ~]$ alias mcsmysql='/home/guest/mariadb/columnstore/mysql/bin/mysql --defaults-extra-file=/home/guest/mariadb/columnstore/mysql/my.cnf -u guest'
[guest@localhost ~]$ mcsmysql
