[build.webkit.org] Ensure that steps names are valid buildbot identifiers
We are planning to upgrade build.webkit.org to latest buildbot. In buildbot 0.9+ step name is an identifier and can not contain space.
As per http://docs.buildbot.net/0.9.8/manual/installation/nine-upgrade.html#identifiers :
"An "identifier" is a nonempty unicode string of limited length, containing only ASCII alphanumeric characters along with - (dash) and _ (underscore), and not beginning with a digit."
We should rename all the step names to not contain any space.
