scripts/contrib/build-perf-test.sh: add a script for build performance tracking
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.
