sigaction(2),sigwait(2),sigwaitinfo(2): Remove [EFAULT] error condition.
Passing an invalid pointer results in undefined behaviour.
The wrappers in libthr access some of the data pointed to by the arguments
in userland, so that an invalid pointer will cause a signal and not an
[EFAULT] error return.
Furthermore, if the [EFAULT] error occurs when the kernel is writing, it is
not a proper error in the sense that the call still commits (changing the
signal disposition or accepting the signal).
