x86, build: Do not set the root_dev field in bzImage
This has been obsoleted by the root= commandline and the rdev utility for many, many years. People who still depend on this will surely have a copy of the rdev utility around, the rest of the world gets rid of another piece of buildhost-dependent data in the build. Thanks to Paul Bolle for the build.c cleanup.
