You're just looking to rotate the fitting down, 30-45 degrees or so, right?
I would wrap the fixed piece of 'pipe' at the banjo fitting with a rag, grab it with a pair of channeloks or such and attempt to rotate the fitting (use some sense) while loosening the bolt slightly (just enough to allow you to rotate it).
Then snug that bolt up, be careful, it just needs to not leak--don't get all bad ass on the end of the wrench or you'll be looking for a replacement master cylinder.
