[crosperf] Add phony image testing, for easier package development.
Using a 'real' bad image for bisecting tool development makes it
very slow because it often requires manual intervention to push
images onto device and to verify if image is good or bad.
This CL creates a phony good/bad test that just looks at the md5 hash
value of Chrome package, allowing testing to be done with two good images,
which greatly simplifies bisecting tool development.
BUG=None
TEST=Tested these scripts individually in my chroot.

+# This script is intended to be used by binary_search_state.py, as
+# part of the binary search triage on ChromeOS packages. It is to be
+# used for testing/development of the binary search triage tool
+# itself. It waits for the install script to build and install the
+# image, then checks the hash of the chrome package being used to build.
+# If the hash matches the test hash, then the image is 'good',
+# otherwise it is 'bad'. This allows the rest of the bisecting tool
+# to run without requiring help from the user (as it would if we were
+# dealing with a real 'bad' image).
