    glib/tests/enviroment.c: Fix running on Windows
    
    Don't attempt to insert environmental variables in the hash table during
    the test listenv that is an empty string, as GetEnvironmentStringsW() also
    returns special enviroment variables which have empty strings as their
    variable names, at least on Windows 7 and 8.
