s390: Implement dump-guest-memory support for target s390x
With this patch dump-guest-memory on s390 produces an ELF formatted,
crash-readable dump.
In order to implement this, the arch-specific part of dump-guest-memory
was added:
target-s390x/arch_dump.c contains the whole set of function for writing
Elf note sections of all types for s390x.
