[PATCH] ntdll: Add SIGQUIT to server block set.

[Paul Gofman]

Receiving SIGQUIT for forced thread termination may leave sync
objects (like virtual_mutex) locked.

    While the issue I observed in the referenced bug (happening during the process termination only)
    can be solved in different ways, I suppose protecting the locks from SIGQUIT is preferred
    because the thread can also be aborted the same way with NtTerminateThread apart from the
    whole process tear down.
