Make simple probes work even without KPROBES in the kernel.
Without KPROBES very little works atm. But stack.c file is unconditionally
imported, while these two functions are only used through context-unwind.stp.
This at least lets us do simple sanity checks on "plain" kernels.
* runtime/stack.c (_stp_stack_print, _stp_stack_snprint):
Wrap in #if defined (CONFIG_KPROBES).
