This script runs a series of builds (core-image-sato by default) with
and without sstate cache and collects some metrics (time and size currently).
It takes a commit as argument (-c <rev>) and measures wall clock for
bitbake core-image-sato and virtual/kernel.

Append results from each run to a single file in order to keep a history.
Also do some cosmetic changes and fix some whitespace.

Adds a -p option to allow cherry-picking of fix revisions.
Removes the final build/sstate directories to stop running out of space.
Runs subsequent tasks even if one test fails.
