cbfstool: relocate FSP blobs on cbfstool add

When adding an FSP blob relocate it to its final
destination. This allows FSP to not be hard coded in
the cbfs. In order for the include paths to work
correctly w/ the edk 2 headers we need to supply
a neutered ProcessorBind.h to match up with the
tool environment such that one can get the UEFI
Platform Initialization type definitions.

BUG=chrome-os-partner:44827
BRANCH=None
TEST=Built glados and booted. Also added FSP with -b and manually
     adjusted location in fsp cache-as-ram. Booted as well.
