[jbosstools-dev] default branch for jbosstools-build-ci set to jbosstools-4.3.x

[Max Rydahl Andersen]

hey,

just a fyi that https://github.com/jbosstools/jbosstools-build-ci now 
defaults to jbosstools-4.3.x instead of master.

The `master` branch is by now deprecated for this repository but we 
cannot change it since old builds unfortunately rely directly on the
`master` branch.

thus changing it to be default jbosstools-4.3.x so merges/PR's/browsing 
stop defaulting to master which should not be changing anyways ;)

Let me know if it gives problems.
