check_link_map: fix check for app memory
This script was assuming that all XIP data copied sections
were contiguous. However with application memory partitioning
enabled, this is not the case; in between the kernel data sections
and the app data sections will be the kernel's BSS and noinit.
As a quick fix, reset the last section compared if we encounter
the kernel's BSS section.
