This fixes issue #37 which would cause a build to fail if a build was
previously executed, and the artifacts from that build were not deleted.
Issue #37: Patch lorax source

Before we were patching lorax directly on the system with a patch in

We will also drop the old patch from support.
Issue #37: Build and install our own lorax in bootstrap

Remove lorax from list of RPMs to install using RHN in bootstrap and

bootstrap process.
