MDEV-11104 Fix client to correctly retrieve current user name on Windows

Browse source 
Prior to this patch name of the user was  read from environment variable
USER, with a fallback to 'ODBC', if the environment variable is not set.

The name of the env.variable is incorrect (USERNAME usually contains current
user's name,  but not USER), which made client to  always determine
current user as 'ODBC'.

The fix is to use GetUserName() instead.
