BaseTools: Fix Segmentation fault: 11 when build AppPkg with XCODE5 

it is a bug in mtoc setting the size of the debug directory entry to
the size of the .debug section, not the size of the
EFI_IMAGE_DEBUG_DIRECTORY_ENTRY. It was causing a loop to iterate and
get bogus EFI_IMAGE_DEBUG_DIRECTORY_ENTRY data and pass that to
memset() and boom.
