build-perf-test.sh: add eSDK testing

Add simple initial eSDK test. Currently, only download size and
installation time of eSDK is measured. The eSDK to be tested is
generated from the same image that the other tests are run for. This
patch will add two new fields to the global results log and that needs
to be taken into account when examining the results.
