Create the MariaDB wmcore unittest database with the current unix user

[amaltaro]

Fixes #10926

Status

ready

Description

From the docker build log:

Info: Using unique option prefix 'sock' is error-prone and can break in the future. Please use the full name 'socket' instead.
ERROR 1044 (42000) at line 1: Access denied for user ''@'localhost' to database 'wmcore_unittest'

there is something strange with the command above.

The unittest user name is explicitly passed in the command line, still it sees nothing (maybe the sock command...) anyhow, since this is all executed during the deployment, we can simply modify it to use the current unix user (`$USER).

Is it backward compatible (if not, which system it affects?)

YES

I managed to test it with my gitlab/docker area and the images have been successfully built and unit tests can run.
Erik, feel free to leave any comments and I can follow those up later.
