x86,kprobes: Fix optprobe trampoline to generate complete pt_regs
Currently the optprobe trampoline template code ganerate an
almost complete pt_regs on-stack, everything except regs->ss.
The 'regs->ss' points to the top of stack, which is not a
valid segment decriptor.
As same as the rethook does, complete the job by also pushing ss.
