Prevents triggering an ASSERT_CURIOSITY for duplicated elf headers for debug DR builds on AArch64 systems. It is possible for small modules (less than 1 page of disk space) to have multiple LOAD data segments. Since these segments are mapped from a single disk page they will all have an elf header. The triggered assertion assumed that there can only be one data segment. Extends this assertion check to accommodate for more than one data segments.

Fixes: #4256 (closed)
