The flatload loader sets the end_code field in the image_info struct
incorrectly, due to a typo.
This is a very long-standing bug (dating all the way back to when
the bFLT loader was added in 2006), but has gone unnoticed because
(a) most people don't use bFLT binaries
(b) we don't actually do anything with the end_code field, except
print it in debugging traces and pass it to TCG plugins
Fix the typo.

Applied to my linux-user-for-7.1 branch.
