Add some simple regression tests for /sbin/rcorder

[ngie]

Summary

This is being used for to verify behavior of a proof of concept I'm developing
to start/shutdown services in a parallelized manner using the basic
framework/format used by rcorder(8).

Obtained from: https://github.com/ngie-eign/rcorder3/tree/master/test

Test Plan

That's a lot of tiny files! Would it be possible and desirable to reduce the file count by using here documents or something?

My goal is to have test input files that I can use for generic testing in https://github.com/ngie-eign/rcorder3/tree/master/test, which I'm going to write a PoC for in python, then write a more finalized solution in C++, once I get buy-off from other folks on the general approach I'm taking.

I don't have time to work on rcorder(8) these days (that was the hope with this change) :/..
