subsys: dfu: Allow to use imgtool-based headers

It is possible to add MCUboot header through --pad-header option.
In such cases, the FLASH_LOAD_OFFSET does not point to the begining of
the slot, but to the beginning of the executable area, thus the check
for the active slot should use ranges instead of exact values.
