Add 'build' settings option and xbuddy image format.

This patch updates Crosperf to add the 'build' tag in the
experiment file, and to allow that field to contain xbuddy
syntax for using trybot and/or official builds in the test runs.
It also adds a bit more checking to make sure we have everything
necessary for running 'cros flash' before attempting to use it.

BUG=None
TEST=I have run this using an experiment file that compares a local
image, a trybot image and an official image against each other.  It
all worked.
