Add defaultbranch to .gitreview

Without having different values in different branches,
"git review" has trouble contributing to non-master branches.

Here is a console output of what happens without this:

vrpolak@ds:~$ git clone ssh://vrpolak@gerrit.fd.io:29418/csit.git

When you have resolved this problem, run "git rebase --continue".
If you prefer to skip this patch, run "git rebase --skip" instead.
To check out the original branch and stop rebasing, run "git rebase --abort".
Could not pick 39ce5d87070867c5a906e2a2ed8a683f975289f4
It is likely that your change has a merge conflict. You may resolve it in the working tree now as described above and then run 'git review' again, or if you do not want to resolve it yet (note that the change can not merge until the conflict is resolved) you may run 'git rebase --abort' then 'git review -R' to upload the change without rebasing.
