tracing/kprobes: Add $ prefix to special variables
Add $ prefix to the special variables(e.g. sa, rv) of kprobe-tracer.
This resolves consistency issues between kprobe_events and perf-kprobe.
The main goal is to avoid conflicts between local variable names of
probed functions, used by perf probe, and special variables used
in the kprobe event creation interface (stack values, etc...) and
also available from perf probe.
ie: we don't want rv (return value) to conflict with a local variable
named rv in a probed function.
