devel/buildbot*: Update to 0.9.11, Add buildbot-grid-view
- Update to buildbot 0.9.11
- Add required devel/py-buildbot-grid-view dependency
- Clean up stuff from individual Makefiles that was copy/pasted from the main buildbot Makefile
- buildbot-www, buildbot-grid-view, buildbot-console-view, buildbot-waterfall-view cannot be tested outside of buildbot, so remove stuff from their Makefiles to simplify.
