vboot: inject vboot loader for stage loading

As previously done the vboot loader can be optionally
inserted in the stage loading logic in order to
decide the source of each stage. This current patch
allows for verstage to be loaded and interrogated
for the source of all subsequent stages. Additionally,
it's also possible to build this logic directly into
one of the additional stages.

Note that this patch does not allow x86 to work.
