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.
