rS340027: Don't allow debuggers to modify SSTATUS, only to read it.

Test Plan

basic gdb of live processes still works. Trying to set $status in gdb doesn't now fails to do anything. (I didn't actually try it on an old kernel to see what would have happened, but I supsect it wouldn't have worked out well.)
