exceptor: Add SA_ONSTACK flag the POSIX backend #802

Add the SA_ONSTACK flag to handle situations where and alternative signal stack has been configured using sigaltstack. In the situations where no alternative stack was configured, this behaves as if the flag has not been set.

Looks like older QNX versions don't support SA_ONSTACK?
