Fix sigaction reporting on non-x86 architectures

If SA_RESTORER is not defined by libc headers but defined by kernel
headers, use the definition provided by kernel headers for proper
sigaction decoding.

* signal.c [!SA_RESTORER]: Define to ASM_SA_RESTORER if the latter is
defined, regardless of architecure.
