vboot: split class in library and stage

The build system includes a bunch of files into verstage that
    also exist in romstage - generic drivers etc.
    These create link time conflicts when trying to link both the
    verstage copy and romstage copy together in a combined configuration,
    so separate "stage" parts (that allow things to run) from "library" parts
    (that contain the vboot specifics).
