    Bug #12917164 DROP USER CAN'T DROP USERS WITH LEGACY
        UPPER CASE HOST NAME ANYMORE

    Description:
    It is not possible to drop users with host names with upper case
    letters in them. i.e DROP USER 'root'@'Tmp_Host_Name'; is failing
    with error.

    Analysis: Since the fix 11748570 we came up with lower case hostnames
    as standard. But in the current bug the hostname is created by
    mysql_install_db script is still having upper case hostnames.
    So, if we have the hostname with upper case letters like(Tmp_Host_Name)
    then we will have as it is stored in the mysql.user table.
    In this case if use "'DROP USER 'root'@'Tmp_Host_Name';" it gives
    error because we do compare with the lower case of hostname since the
    11748570 fix.

    Fix: We need to convert the hostname to lower case before storing into
    the mysql.user table when we run the mysql_install_db script.
