linux-user: Fix wrong type used for argument to rt_sigqueueinfo

Browse Source 
The third argument to the rt_sigqueueinfo syscall is a pointer to
a siginfo_t, not a pointer to a sigset_t. Fix the error in the
arguments to lock_user(), which meant that we would not have
detected some faults that we should.
