Add withMerge flag for gitSSHCheckout step

Rather than merge the changes to be built into a branch which
tracks the remote I want to push to, it checks out one rev and
merges the others on, resulting in a detached HEAD.

Some tools expects to be run on a specific branch, and it
fails because the repo isn't in that state.
