1. Please describe the problem:

mysql_setpermission fails to connect to local mariadb, claiming that 
DBI connect(';host=localhost;port=3306','newuser',...) failed: Connection error: port cannot be specified when host is localhost or embedded at /usr/bin/mysql_setpermission line 116.

the DBI connect string comes from the mysql_setpermission command defaults (was not a user input)


2. Specify used package versions
mariadb-server-utils-10.5.10-1.fc34


5. Can you reproduce this issue? If so, please provide the steps to reproduce the issue below:
# systemctl start mariadb
# mysql
mysql> CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
mysql> GRANT ALL PRIVILEGES ON *.*  TO 'newuser'@'localhost' WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES;
# mysql_setpermission  --user newuser
