rcutorture: Copy out ftrace into its own console file
When debugging it can be difficult to quickly find the ftrace dump
withiin the console log, which in turn makes it difficult to process it
independent of the result of the console output. This commit therefore
copies the contents of the buffers into its own file to make it easier
to locate and process the ftrace dump. The original ftrace dump is still
available in the console log in cases where it is more convenient to
process it there, for example, when you have a script that processes
console output as well as ftrace-dump data.
