Make gate-ceilometer-python34 only run on master branch

d64ff557f774b2b16a755675c9c4f34ddd7c1dd3 originally made the py33 job
only run on master but that was before stable/juno existed. The py34 job
is failing on stable/juno because a
ceilometer dependency (happybase) doesn't support py3 yet and the
ceilometer tox.ini doesn't have a py34 target on stable/juno, that was
added to master with commit 8883fa9801579c28c4b36fca611008fc81ca1045.

We could backport the tox.ini change to stable/juno but there doesn't
seem to be much point in running a handful of py3 tests for ceilometer
on stable so make the job only run on master.

There is also some related history for stable/icehouse in change
