Added logbuffer helper package

This adds a small package which is used to store logs for other
binaries we're calling. It's an in-memory non-depleting ring buffer
capable of directly taking in a stream (for example from stdout).
For reliability it has bounded total memory consumption.
It offers a simple interface to get the last n log lines out.

Test Plan: Has 100% test coverage built-in

Bug: T667
