executor: arm64: sys/linux: allocate 1024 pages for guest address space
Pass 1024 pages of memory to both syz_kvm_setup_syzos_vm() and
syz_kvm_setup_cpu$arm64() to make sure that:
- there is enough memory for guest allocations (e.g. ITS pages)
- host can tamper with that memory, provoking more bugs
