sh/boot: add static stack-protector to pre-kernel
The sh decompressor code triggers stack-protector code generation when
using CONFIG_CC_STACKPROTECTOR_STRONG. As done for arm and mips, add a
simple static stack-protector canary. As this wasn't protected before,
the risk of using a weak canary is minimized. Once the kernel is
actually up, a better canary is chosen.
