vboot: allow for dynamic work buffers

Browse Source 
The vboot library currently relies on link-time known
address and sizes of the work buffer.  Not all platforms
can provide such semantics. Therefore, add an option
to use cbmem for the work buffer. This implies such platforms
can only do verification of the firmware after main memory
has been initialized.
