In https://trac.webkit.org/r245359 build.webkit.org started using Tools/BuildSlaveSupport/Shared folder. To support that the shallow checkout on build.webkit.org was moved to Tools/BuildSlaveSupport We need to update the basedir in master.cfg accordingly. It was updated locally on the build.webkit.org machine, but wasn't committed to repo yet.

Similar to how newer versions of buildbot create this variable https://github.com/buildbot/buildbot/blob/master/master/buildbot/scripts/buildbot_tac.tmpl#L21 and similar to https://trac.webkit.org/browser/webkit/trunk/Tools/BuildSlaveSupport/ews-build/buildbot.tac#L6
