mshtml/tests: Some tests require that the user interface be in English.

[Francois Gouget]

With MUI versions of Windows checking for the default user language id is insufficient.
Skip the system language id check as it is irrelevant here.

Well, I don't see how the system language id would be relevant and it's 
not needed in my French NT4 or Windows 7 VMs. So I'd like a good 
rationale to leave it in.
