Updated to latest rawhide version, also slimmed down the build so it will now build in less than an hour (20 min or so on my machine using mock).

Also, a fix from chromium's package in fedora is still needed to resolve the chromium-libs-media issue. Also the mixed-use-of-spaces-and-tabs warning is a false positive.
