cover toaster: buildinfohelper Handle regex pattern paths

We were presuming that all the layer dependency information was of the form "^/path/to/layer" so we were just stripping the leading "^" off of the layer information when we were matching the layer priorities to the toaster database. This patch splits out the priorities layer match which gets a regex from the task/recipe match which gets a path.

In V3, I added a doc string to explain pathRE and used Michael's name for the sort function.

Thanks, do you think this should be submitted for morty and master?
