scripts/gdb/symbols: determine KASLR offset on s390 during early boot
Using lx-symbols during s390 early boot fails with:
Error occurred in Python: 'utf-8' codec can't decode byte 0xcb in position 0: invalid continuation byte
The reason is that s390 decompressor's startup_kernel() does not create
vmcoreinfo note, and sets vmcore_info to kernel's physical base. This
confuses get_vmcore_s390().
Fix by handling this special case. Extract vm_layout.kaslr_offset from
the kernel image in physical memory, which is placed there by the
decompressor using the __bootdata_preserved mechanism, and generate a
synthetic vmcoreinfo note from it.
