openssl-native: disable execstack flag to prevent problems with SELinux

The execstack flag gets set on libcrypto.so by default which causes SELinux
to prevent it from being loaded on systems using SELinux, which includes
Fedora. This patch disables the execstack flag. (Note: Red Hat do this in
their openssl packaging.)
