Previously there were 2 paths in linking ramstage. One was used for
RELOCATABLE_RAMSTAGE while the other was fixed location. Now that
rmodtool can handle multiple secitons for a single proram segment
there's no need for linking ramstage using lib/rmodule.ld. That
also means true rmodules don't have symbols required for ramstage
purposes so fix memlayout.h. Lastly add default rules for creating
rmod files from the known file names and locations.
BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built rambi. Inspected ramstage.debug as well as rmodules
created during the build.
