util/cbfstool: calculate cbfs file size for xip stages
The initial lookup for cbfs location for xip stages is implicitly
using the ELF size assuming it's relatively equivalent. However,
if the ELF that is being converted contains debug information or
other metadata then the location lookup can fail because the ELF is
considerably bigger than the real footprint.
