aout32 coredump compat fix
dump_seek() does SEEK_CUR, not SEEK_SET; native binfmt_aout handles it correctly (seeks by PAGE_SIZE - sizeof(struct user), getting the current position to PAGE_SIZE), compat one seeks by PAGE_SIZE and ends up at PAGE_SIZE + already written... Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
