sigaltstack: support SS_AUTODISARM for CONFIG_COMPAT
commit 441398d378f29a5ad6d0fcda07918e54e4961800 upstream.
Currently SS_AUTODISARM is not supported in compatibility mode, but does
not return -EINVAL either. This makes dosemu built with -m32 on x86_64
to crash. Also the kernel's sigaltstack selftest fails if compiled with
-m32.
This patch adds the needed support.
