vboot_ref: Reshuffle parallel flashrom impl

Bring sub-process and libflashrom wrapper implementations
under the common host/lib path to later be reconciled.
The WP implementation is left separated out due to the
lack of a libflashrom WP implementation which creates
circular dependencies for the moment.
