alpha: fix osf_wait4() breakage
kernel_wait4() expects a userland address for status - it's only
rusage that goes as a kernel one (and needs a copyout afterwards)
[ Also, fix the prototype of kernel_wait4() to have that __user
annotation - Linus ]
Fixes: 92ebce5ac55d ("osf_wait4: switch to kernel_wait4()")
Cc: stable@kernel.org # v4.13+
