* polymer-css-build: 0.0.9 -> 0.1.2
* vulcanize: 1.15.2 -> 1.15.4

Updating vulcanize allows us to trim our local patch.  I also renamed
patch_vulcanize.diff to chromium_vulcanize.patch as "chromium.patch"
seems like a more common file name for applying Chromium-specific
changes to third_party code.
