[sim] Fix mbuild build breaker in sim-cpu.c

When running gdb/gdb_mbuild.sh, I run into:
...
src/sim/aarch64/../common/sim-cpu.c: In function 'sim_cpu_free':
src/sim/aarch64/../common/sim-cpu.c:64:3: error: implicit declaration of \
  function 'free' [-Werror=implicit-function-declaration]
   free (cpu);
   ^~~~
src/sim/aarch64/../common/sim-cpu.c:64:3: error: incompatible implicit \
  declaration of built-in function 'free' [-Werror]
src/sim/aarch64/../common/sim-cpu.c:64:3: note: include '<stdlib.h>' or \
  provide a declaration of 'free'
...

Fix this by adding "#include <stdlib.h>".

Tested by gdb/gdb_mbuild.sh -e aarch64-elf.
