Since its inception elf2dmp has checked MZ signatures within an address space above IDT[0] interrupt vector and took first PE image found as Windows Kernel. But in Windows Server 2022 memory dump this address space range is full of invalid PE fragments and the tool must check that PE image is 'ntoskrnl.exe' actually. So, introduce additional validation by checking image name from Export Directory against 'ntoskrnl.exe'.
