[APL] Add BP1 partition size check in StitchLoader.py

Current SitchLoader.py does not verify if the BP1 partition size
is big enough to hold a duplicated BPDT from BP0. And it will
result in invalid BPDT partition format if it occurs. This patch
added a check so that it will error out if insufficient space is
detected.
