kernel-tracing: fixup denglish, add perf probe, tracing_on

There were some german and german-like words lingering. Fix these
to proper english.

Show the use of "perf probe" for adding kprobes and uprobes.

Move the tracing_on()/tracing_off() slide next to the trace_printk().
It makes more sense there since we are talking about writing kernel
code for tracing.
