[build.webkit.org] Update RunWebKitTests step for new buildbot

[Aakash Jain]

We are planning to upgrade build.webkit.org to latest Buildbot. We should update RunWebKitTests as per new Buildbot, e.g.:
use logobserver instead of cmd.logs['stdio'].getText()
use getResultSummary instead of getText/getText2

Also we should take this opportunity to switch to logobserver.LineConsumerLogObserver which is more efficient in processing large logs than logobserver.BufferLogObserver.

Most of this code is copied from code written by Dean in another repository.

Can we populate this changelog with a bit more information?

Were we not using the log observer previously? Or does that option not exist for buildbot 0.8?

Yeah, Buildbot 0.8 didn't had this logobserver module.
