Title: Do not catch GeneratorExit exception

On buildbot 0.8.8 in rare conditions, we hit:

File "/data/buildbot/twisted/internet/threads.py", line 49, in deferToThreadPool
threadpool.callInThreadWithCallback(onResult, f, *args, **kwargs)
File "/data/buildbot/twisted/python/threadpool.py", line 148, in callInThreadWithCallb

File "//usr/lib/python2.7/Queue.py", line 138, in put
self.not_empty.notify()
File "//usr/lib/python2.7/threading.py", line 392, in notify
for waiter in waiters:
--- ---
File "/data/buildbot/buildbot/process/buildstep.py", line 605, in _startStep_3
result = yield defer.maybeDeferred(self.start)
exceptions.GeneratorExit:

this applies the fix from http://trac.buildbot.net/ticket/2395#comment:10 to master/buildbot/process/buildstep.py
