cpu: Directly use cpu_write_elf*() fallback handlers in place

Browse source 
No code directly accesses CPUClass::write_elf*() handlers out
of hw/core/cpu.c (the rest are assignation in target/ code):

  $ git grep -F -- '->write_elf'

  target/s390x/cpu.c:522:    cc->write_elf64_note = s390_cpu_write_elf64_note;

Check the handler presence in place and remove the common fallback code.
