component/headless-chromium: create test version for faster development

component/headless-chromium-test/buildout.cfg

+# This is a dummy version that fetches a precompiled binary, to
+# facilitate testing. This way, we can test software/headless-chromium
+# without having to wait for component/headless-chromium to finish
+# compiling each time. This component will be deleted before the merge
+# request is finalized.
